Consider the function f (x) = x^2+2x-15. what are the x-intercepts of the function?

x=3 and x = - 5

Step-by-step explanation:

x^2+2x-15

Find the numbers that can be multiplied to equal the last term and added to equal the second term: x^2+5x-3x-15

Factor: x (x+5) - 3 (x+5)

Then you get: (x-3) (x+5) = 0

Answer: x=3 and x=-5
