You have come to the correct place if you are looking to solve the quadratic equation 16x squared minus 8x minus 99 equals 0, also known as 16x² - 8x - 99 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 16x^2 - 8x - 99 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 16x² - 8x - 99 = 0.
Below is 16x squared minus 8x minus 99 in factored form. As you can see, 16x² - 8x - 99 has been grouped into two sets of parentheses.
(4x - 11)(4x + 9)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 16x^2 - 8x - 99 = 0.
(4x - 11) = 0
x1 = 2 3/4
(4x + 9) = 0
x2 = -2 1/4
