You have come to the correct place if you are looking to solve the quadratic equation negative 13x squared minus 80x minus 67 equals 0, also known as -13x² - 80x - 67 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to -13x^2 - 80x - 67 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve -13x² - 80x - 67 = 0.
Below is negative 13x squared minus 80x minus 67 in factored form. As you can see, -13x² - 80x - 67 has been grouped into two sets of parentheses.
-(x + 1)(13x + 67)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to -13x^2 - 80x - 67 = 0.
(x + 1) = 0
x1 = -1
(13x + 67) = 0
x2 = -5 2/13
