You have come to the correct place if you are looking to solve the quadratic equation negative 80x squared minus 100x minus 30 equals 0, also known as -80x² - 100x - 30 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to -80x^2 - 100x - 30 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve -80x² - 100x - 30 = 0.
Below is negative 80x squared minus 100x minus 30 in factored form. As you can see, -80x² - 100x - 30 has been grouped into two sets of parentheses.
-(20x + 10)(4x + 3)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to -80x^2 - 100x - 30 = 0.
(20x + 10) = 0
x1 = -1/2
(4x + 3) = 0
x2 = -3/4
