What is the quadratic formula and how is it used to solve quadratic equations?

The quadratic formula is \[x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\] where \(a\), \(b\), and \(c\) are coefficients of a quadratic equation in the form \(ax^2 + bx + c = 0\). This formula is used to find the roots of a quadratic equation, which are the values of \(x\) that satisfy the equation. By plugging in the coefficients into the formula, you can solve for the values of \(x\) that make the equation true. The \(\pm\) sign indicates that there are two possible solutions to a quadratic equation, accounting for any possible distinct roots.

What are the steps to graphing a linear equation in slope-intercept form?

To graph a linear equation in slope-intercept form (y = mx + b), start by plotting the y-intercept (b) on the y-axis. Then, use the slope (m) to find a second point by moving up or down according to the rise over run of the slope. Connect the two points with a straight line to complete the graph of the linear equation. Repeat the process for confirmation and further accuracy if needed by selecting more points and connecting them.

How do you simplify rational expressions by factoring?

To simplify rational expressions by factoring, factor both the numerator and the denominator completely. Then, identify any common factors between the numerator and the denominator and cancel them out. Finally, write the simplified expression with any remaining factors in the numerator and denominator. This process helps to reduce the expression to its simplest form, making it easier to work with and understand.

What are the properties of exponential functions and how do you graph them?

Exponential functions have the general form f(x) = a*b^x, where 'a' and 'b' are constants and 'b' is the base. Some key properties of exponential functions include rapid growth or decay, never crossing the x-axis, and having a horizontal asymptote at y = 0. To graph an exponential function, plot a few key points, such as (0, a) for the y-intercept and (1, a*b) for another point, then connect these points smoothly as the graph either rises or falls exponentially depending on the base 'b'.

How do you solve systems of linear equations using substitution?

To solve systems of linear equations using substitution, start by solving one of the equations for one of the variables. Then, substitute this expression into the other equation. Solve for the remaining variable and substitute its value back into the first equation to find the value of the other variable. This method helps to find the unique solution to the system of equations.

What is the difference between arithmetic and geometric sequences?

Arithmetic sequences are sequences where each term is obtained by adding a fixed number to the previous term, whereas geometric sequences are sequences where each term is obtained by multiplying the previous term by a fixed number. In arithmetic sequences, the difference between consecutive terms remains constant, while in geometric sequences, the ratio between consecutive terms remains constant.

How do you solve absolute value equations and inequalities?

To solve absolute value equations and inequalities, first isolate the absolute value expression on one side of the equation or inequality. Then, set up two possible equations or inequalities and solve for both the positive and negative solutions. Finally, check if the solutions satisfy the original equation or inequality to ensure accuracy. Remember to handle each case separately and consider both possibilities when solving absolute value equations and inequalities.

What is the concept of complex numbers and how do you perform operations with them?

Complex numbers consist of a real part and an imaginary part expressed as a + bi, where "a" is the real part and "bi" is the imaginary part with "i" being the imaginary unit (?-1). Operations with complex numbers like addition, subtraction, multiplication, and division are performed by treating the real and imaginary parts separately and then combining them accordingly. Addition and subtraction are performed by adding/subtracting the real parts and separately the imaginary parts. Multiplication involves distributing each term of one number over the other and simplifying the resulting expression. Division is typically done by multiplying the numerator and denominator by the conjugate of the denominator to eliminate the imaginary part in the denominator.

How do you solve logarithmic equations and inequalities?

To solve logarithmic equations, first isolate the logarithm on one side of the equation. Then rewrite the logarithm as an exponent to eliminate the logarithm. Solve for the variable based on the exponents. For logarithmic inequalities, after isolating the logarithm on one side, remember that the inequality sign changes direction when both sides are raised to the same base. Make sure to check for any extraneous solutions that may arise from taking logarithms of negative numbers or zero.

What are the properties of rational exponents and how do you simplify expressions with them?

Rational exponents have two key properties: (1) a^(m/n) is the same as the n?a^m and (2) (a^m)^n is the same as a^(m*n). To simplify expressions with rational exponents, apply these properties to rewrite the expression in a form where the base is raised to an integer power. Then, calculate the value of the integer power using the rules of exponents. Remember to simplify the expression further by finding common factors or simplifying radicals if needed.
