Question 380363: Find the zeros of . The zeros of f(x) are

The zeros of a function are the values of x that would make the function equal 0.
The easiest way to find the zeros in your function is to factor it. 7 * -1 = -7 and 7 + -1 = 6, so this will factor as f(x) = (x + 7)(x - 1)
The zeros can be found by setting this equal to 0: (x + 7)(x - 1) = 0
When two numbers multiply to 0, one of them must be 0. Thus, either x + 7 = 0 or x - 1 = 0. Solve each for x, and x = -7 or x = 1. Those are your zeros. You can check by plugging each into the original equation for x; you'll end up with 0 for each!
