What is the quadratic formula?

The quadratic formula is given by x = (-b ± ?(b^2 - 4ac)) / 2a, where a, b, and c are coefficients of a quadratic equation in the form ax^2 + bx + c = 0.

How do you solve systems of equations using elimination?

To solve systems of equations using elimination, you need to choose a variable to eliminate by adding or subtracting the equations. This creates a new equation with one fewer variable, making it easier to solve for the remaining variable. Next, solve for the remaining variable using the new equation. Once you have the value for one variable, substitute it back into one of the original equations to find the value of the other variable. This process helps to find the solution to the system of equations by eliminating variables one step at a time.

What is the difference between an arithmetic sequence and a geometric sequence?

An arithmetic sequence is a series of numbers where each term is generated by adding a fixed number (common difference) to the previous term, while a geometric sequence is a series of numbers where each term is generated by multiplying the previous term by a fixed number (common ratio). In essence, in an arithmetic sequence, the difference between consecutive terms is constant, while in a geometric sequence, the ratio between consecutive terms is constant.

How do you simplify expressions with exponents?

To simplify expressions with exponents, you can use the rules of exponents. When multiplying like bases, you can add the exponents. When dividing like bases, you can subtract the exponents. When raising a power to a power, you multiply the exponents. Additionally, any base raised to the power of 0 equals 1. Applying these rules will help you simplify expressions with exponents efficiently.

What are the properties of logarithms?

The properties of logarithms include the product property (log(a*b) = log(a) + log(b)), the quotient property (log(a/b) = log(a) - log(b)), the power property (log(a^b) = b * log(a)), the base switch property (log_a(b) = log_c(b) / log_c(a)), and the inverse property (log_a(a^x) = x). These properties are helpful in simplifying logarithmic expressions and solving equations involving logarithms.

How do you solve inequalities and graph the solution on a number line?

To solve inequalities, you need to isolate the variable on one side of the inequality sign. Treat it like solving an equation, but remember to reverse the inequality sign if you multiply or divide by a negative number. Once you have the solution, you can graph it on a number line. Use an open circle for "<" or ">", a filled circle for "?" or "?", and shade to the right for ">" or "?", or to the left for "<" or "?", based on the inequality.

What is the unit circle and how is it used in trigonometry?

The unit circle is a circle with a radius of 1 centered at the origin of a coordinate plane. In trigonometry, the unit circle is used to define the trigonometric functions sine, cosine, and tangent for any angle. By associating points on the unit circle with specific angles, trigonometric values can be calculated easily. The unit circle also helps in understanding the relationships between the trigonometric functions and provides a geometric interpretation of these functions.

What is the binomial theorem and how is it used to expand binomial expressions?

The binomial theorem is a mathematical formula that describes how to expand a binomial expression raised to a positive integer exponent. It states that for any two numbers a and b, and a non-negative integer n, the expansion of (a + b)^n can be found using the formula that includes binomial coefficients. This theorem allows you to efficiently compute the terms in the expanded form of binomial expressions without having to multiply each term individually, making it a powerful tool in algebra and calculus for simplifying and solving equations.

How do you find the inverse of a function and check for symmetry?

To find the inverse of a function, switch the roles of x and y and solve for y. If the function is symmetric with respect to the line y = x, then the original function and its inverse will be reflections of each other over the line y = x. You can check for symmetry by plotting the function and its inverse on the same graph and seeing if they are mirror images of each other across the line y = x.

What is the difference between domain and range in relation to functions?

In relation to functions, the domain refers to the set of all possible input values that can be plugged into the function, while the range refers to the set of all possible output values that the function can produce. The domain is the set of x-values, or inputs, and the range is the set of y-values, or outputs, of a function. Essentially, the domain specifies where the function is defined, and the range specifies the possible outcomes of the function based on those inputs.
