You have come to the correct place if you are looking to solve the quadratic equation negative 4x squared minus 22x minus 18 equals 0, also known as -4x² - 22x - 18 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to -4x^2 - 22x - 18 = 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 - 22x - 18 = 0.
Below is negative 4x squared minus 22x minus 18 in factored form. As you can see, -4x² - 22x - 18 has been grouped into two sets of parentheses.
-(2x + 2)(2x + 9)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to -4x^2 - 22x - 18 = 0.
(2x + 2) = 0
x1 = -1
(2x + 9) = 0
x2 = -4 1/2
