You have come to the correct place if you are looking to solve the quadratic equation 30x squared minus 28x minus 98 equals 0, also known as 30x² - 28x - 98 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 30x^2 - 28x - 98 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 30x² - 28x - 98 = 0.
Below is 30x squared minus 28x minus 98 in factored form. As you can see, 30x² - 28x - 98 has been grouped into two sets of parentheses.
(6x - 14)(5x + 7)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 30x^2 - 28x - 98 = 0.
(6x - 14) = 0
x1 = 2 1/3
(5x + 7) = 0
x2 = -1 2/5
