You have come to the correct place if you are looking to solve the quadratic equation 10x squared minus 15x minus 25 equals 0, also known as 10x² - 15x - 25 = 0. Below, we walk you through how to find the answer.
To find the two possible answers to 10x^2 - 15x - 25 = 0, we will start by rewriting the equation in factored form. Then, we will create two separate equations that we can use to solve 10x² - 15x - 25 = 0.
Below is 10x squared minus 15x minus 25 in factored form. As you can see, 10x² - 15x - 25 has been grouped into two sets of parentheses.
(10x - 25)(x + 1)
Next, we set each set of parentheses equal to 0 and solve for x to get the two answers to 10x^2 - 15x - 25 = 0.
(10x - 25) = 0
x1 = 2 1/2
(x + 1) = 0
x2 = -1
