You have come to the correct place if you are looking to solve the quadratic equation 4x squared minus 14x minus 8 equals 0, also known as 4x² - 14x - 8 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 4x^2 - 14x - 8 = 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 - 14x - 8 = 0.
Below is 4x squared minus 14x minus 8 in factored form. As you can see, 4x² - 14x - 8 has been grouped into two sets of parentheses.
(2x - 8)(2x + 1)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 4x^2 - 14x - 8 = 0.
(2x - 8) = 0
x1 = 4
(2x + 1) = 0
x2 = -1/2
