You have come to the correct place if you are looking to solve the quadratic equation 3x squared plus 8x minus 80 equals 0, also known as 3x² + 8x - 80 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 3x^2 + 8x - 80 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 3x² + 8x - 80 = 0.
Below is 3x squared plus 8x minus 80 in factored form. As you can see, 3x² + 8x - 80 has been grouped into two sets of parentheses.
(x - 4)(3x + 20)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 3x^2 + 8x - 80 = 0.
(x - 4) = 0
x1 = 4
(3x + 20) = 0
x2 = -6 2/3
