You have come to the correct place if you are looking to solve the quadratic equation 42x squared minus x minus 76 equals 0, also known as 42x² - x - 76 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 42x^2 - x - 76 = 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 - x - 76 = 0.
Below is 42x squared minus x minus 76 in factored form. As you can see, 42x² - x - 76 has been grouped into two sets of parentheses.
(14x - 19)(3x + 4)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 42x^2 - x - 76 = 0.
(14x - 19) = 0
x1 = 1 5/14
(3x + 4) = 0
x2 = -1 1/3
