Question

What are the zeroes of the function y=3(x-a)(x+b) in terms of a and b?

Answer 1

a, -b

Explanation:

When x is a, the function becomes

`f(a)=3(a-a)(a+b)`

as you see, a-a is 0, and as your whole function is multiplied by this, it makes it 0.

`f(-b)=3(-b-a)(-b+b)`

As you see -b+b is 0, and once again, this would make the whole function 0.
