You have come to the correct place if you are looking to solve the quadratic equation 10x squared minus 6x minus 72 equals 0, also known as 10x² - 6x - 72 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 10x^2 - 6x - 72 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 10x² - 6x - 72 = 0.
Below is 10x squared minus 6x minus 72 in factored form. As you can see, 10x² - 6x - 72 has been grouped into two sets of parentheses.
(2x - 6)(5x + 12)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 10x^2 - 6x - 72 = 0.
(2x - 6) = 0
x1 = 3
(5x + 12) = 0
x2 = -2 2/5
