What is the value of x if x * x + 2x -35 = 0?

There are two correct answers to this question, which are -5 and 7. To solve this equation, one would need to first factor x2 - 2x -35. Factoring is the process of identifying what number can be used to multiply all the numbers together to simplify it. That will give us (x-7) (x-5) equaling 0.

Using the zero product property, we would get x-7 = 0 and x-5 = 0. This property states that if one is zero, the other must be zero as well. From there, we will be able to have our answer of x = - 5 and x= 7.
