Question

Given the function y = x2+ 5x − 6 , list the zeros of the function

Answer 1

Explanation:

First we sould factor out the function:

y=x^2+5x-6

y=(x+6)(x-1)

Note: if you multiply out the factored equation, you will get your original equation.

Now, find what we need to plug in to make it equal 0.

If we plug in -6, then the (x+6) part equals 0. Since we are multiplying by 0, the whole thing equals 0.

If we plug in 1, then the (x-1) part equals 0. Since we are alo multiplying by 0 here, the function comes out to 0.

This means that at x=-6 and x=1 the function comes out to 0.
