You have come to the correct place if you are looking to solve the quadratic equation 4x squared minus 12x minus 55 equals 0, also known as 4x² - 12x - 55 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 4x^2 - 12x - 55 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 4x² - 12x - 55 = 0.
Below is 4x squared minus 12x minus 55 in factored form. As you can see, 4x² - 12x - 55 has been grouped into two sets of parentheses.
(2x - 11)(2x + 5)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 4x^2 - 12x - 55 = 0.
(2x - 11) = 0
x1 = 5 1/2
(2x + 5) = 0
x2 = -2 1/2
