You have come to the correct place if you are looking to solve the quadratic equation 72x squared minus 90x minus 77 equals 0, also known as 72x² - 90x - 77 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 72x^2 - 90x - 77 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 72x² - 90x - 77 = 0.
Below is 72x squared minus 90x minus 77 in factored form. As you can see, 72x² - 90x - 77 has been grouped into two sets of parentheses.
(6x - 11)(12x + 7)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 72x^2 - 90x - 77 = 0.
(6x - 11) = 0
x1 = 1 5/6
(12x + 7) = 0
x2 = -7/12
