Thank You !

Answer 3

pls be trustworthy with ur concepts!!
Example
The factors of x2 + 3x - 4 are:

(x+4) and (x-1)

Why? Well, let us multiply them to see:

(x+4)(x-1) = x(x-1) + 4(x-1)
= x2 - x + 4x - 4
= x2 + 3x - 4
Multiplying (x+4)(x-1) together is called Expanding.

In fact, Expanding and Factoring are opposites:
