You have come to the correct place if you are looking to solve the quadratic equation negative 7x squared plus 30x minus 8 equals 0, also known as -7x² + 30x - 8 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to -7x^2 + 30x - 8 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve -7x² + 30x - 8 = 0.
Below is negative 7x squared plus 30x minus 8 in factored form. As you can see, -7x² + 30x - 8 has been grouped into two sets of parentheses.
-(x - 4)(7x - 2)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to -7x^2 + 30x - 8 = 0.
(x - 4) = 0
x1 = 4
(7x - 2) = 0
x2 = 2/7
