Solve x² - 20x + 91 = 0

You have come to the correct place if you are looking to solve the quadratic equation x squared minus 20x plus 91 equals 0, also known as x² - 20x + 91 = 0. Below, we walk you through how to find the answer.

To find the two possible answers to x^2 - 20x + 91 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve x² - 20x + 91 = 0.

Below is x squared minus 20x plus 91 in factored form. As you can see, x² - 20x + 91 has been grouped into two sets of parentheses.

(x - 13)(x - 7)

Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to x^2 - 20x + 91 = 0.

(x - 13) = 0
x₁ = 13

(x - 7) = 0
x₂ = 7
