You have come to the correct place if you are looking to solve the quadratic equation 2x squared minus 7x minus 4 equals 0, also known as 2x² - 7x - 4 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 2x^2 - 7x - 4 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 2x² - 7x - 4 = 0.
Below is 2x squared minus 7x minus 4 in factored form. As you can see, 2x² - 7x - 4 has been grouped into two sets of parentheses.
(x - 4)(2x + 1)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 2x^2 - 7x - 4 = 0.
(x - 4) = 0
x1 = 4
(2x + 1) = 0
x2 = -1/2
