You have come to the correct place if you are looking to solve the quadratic equation negative 12x squared minus 56x minus 65 equals 0, also known as -12x² - 56x - 65 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to -12x^2 - 56x - 65 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve -12x² - 56x - 65 = 0.
Below is negative 12x squared minus 56x minus 65 in factored form. As you can see, -12x² - 56x - 65 has been grouped into two sets of parentheses.
-(6x + 13)(2x + 5)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to -12x^2 - 56x - 65 = 0.
(6x + 13) = 0
x1 = -2 1/6
(2x + 5) = 0
