You have come to the correct place if you are looking to solve the quadratic equation 30x squared plus 13x minus 36 equals 0, also known as 30x² + 13x - 36 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 30x^2 + 13x - 36 = 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 + 13x - 36 = 0.
Below is 30x squared plus 13x minus 36 in factored form. As you can see, 30x² + 13x - 36 has been grouped into two sets of parentheses.
(10x - 9)(3x + 4)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 30x^2 + 13x - 36 = 0.
(10x - 9) = 0
x1 = 9/10
(3x + 4) = 0
x2 = -1 1/3
