You have come to the correct place if you are looking to solve the quadratic equation 42x squared minus 2x minus 72 equals 0, also known as 42x² - 2x - 72 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 42x^2 - 2x - 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 42x² - 2x - 72 = 0.
Below is 42x squared minus 2x minus 72 in factored form. As you can see, 42x² - 2x - 72 has been grouped into two sets of parentheses.
(6x - 8)(7x + 9)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 42x^2 - 2x - 72 = 0.
(6x - 8) = 0
x1 = 1 1/3
(7x + 9) = 0
x2 = -1 2/7
