Question

The solutions of a quadratic equation are 5 and -1. What is the factored form of a related quadratic function?

Answer 1

f(x)=(x+1)(x-5)

Explanation:

The solutions to a quadratic equation are going to be your x-intercepts, or when y is equal to zero. For y to be zero, all you have to do is have one value equal to zero. When x is 5, (x-5) is equal to zero. When x is -1, (x+1) is equal to zero. This is one example of what your quadratic equation could be.
