What is the quadratic formula?

The quadratic formula is given by x = (-b ± ?(b² - 4ac)) / 2a, where a, b, and c are coefficients of a quadratic equation in the form of ax² + bx + c = 0. This formula is used to find the solutions, or roots, of a quadratic equation by solving for the values of x that satisfy the equation.

How do you solve systems of linear equations?

One way to solve systems of linear equations is through the method of substitution or elimination. By isolating one variable in one equation and substituting it into the other equation, you can find the values of the variables that satisfy both equations simultaneously. Alternatively, you can add or subtract multiples of the equations to eliminate one variable and solve for the remaining variable. Both methods will help you find the unique solution, if it exists, to the system of linear equations.

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically, this is represented as a² + b² = c², where a and b are the lengths of the two shorter sides, and c is the length of the hypotenuse.

How do you find the area of a circle?

To find the area of a circle, you can use the formula A = ?r^2, where A represents the area and r is the radius of the circle. Square the radius, multiply it by ? (pi), and you will have the area of the circle.

What is the difference between permutations and combinations in probability?

Permutations refer to the arrangement of items in a specific order, where the order matters. Combinations, on the other hand, refer to the selection of items without considering the order. Therefore, permutations involve distinct arrangements, while combinations involve selecting a subset of items without regard to their order.

How do you solve logarithmic equations?

To solve logarithmic equations, you first need to isolate the logarithm on one side of the equation. Next, rewrite the logarithm as an exponential equation and solve for the variable. Finally, check your solution by plugging it back into the original logarithmic equation to ensure it satisfies the given equation. Remember to be mindful of any restrictions on the domain of the logarithmic function that could affect your solution.

What is the concept of inverse functions?

Inverse functions are a pair of functions that undo each other's actions. Two functions f and g are inverses if applying one function followed by the other results in the identity function, where f(g(x)) = x for all x in the domain of g and g(f(x)) = x for all x in the domain of f. In other words, if you apply one function and then its inverse to an input, you get back the original input. This concept is important in mathematics and has various applications in areas such as cryptography, physics, and engineering.

How do you factor polynomials using the distributive property?

To factor polynomials using the distributive property, you need to look for common factors in each term of the polynomial and then factor them out. You can often do this by finding the greatest common factor of the terms and pulling it out of the expression using the distributive property. This process helps simplify the polynomial by breaking it down into smaller, more manageable parts.

What are the properties of exponential functions?

Exponential functions are characterized by the presence of a variable in the exponent, rather than the base, leading to rapid growth or decay. They all have a positive base, resulting in continuous, increasing functions. Exponential functions have a horizontal asymptote (y = 0 for growth or a positive constant for decay), are always positive, and exhibit a continuous, smooth curve that may grow or decay at different rates depending on the base and sign of the exponent.

How do you use matrices to solve systems of equations?

To solve systems of equations using matrices, first express the system in matrix form where the coefficients of the variables make up a matrix and the constants make up another matrix. Then, apply matrix operations such as row operations to transform the augmented matrix into reduced row-echelon form. Finally, interpret the resulting matrix to find the values of the variables in the system of equations.
