Question

(a+b)(a-b)what is the final equation of this method
​

Answer 1

THE FINAL EQUATION IS

(a+b)(a-b) = a^2 - b^2

Answer 2

Answer:

a^2-b^2

Step-by-step explanation:

The equation says (a+b)(a-b).

We will product it, and it will be (a^2-ab+ab-b^2)

Then we will get (a^2-b^2)

That is the final equation.

Prove:

a=5, b=3

(5+3)(5-3)

=8(2)

=16

If we use (a^2-b^2)

then we get (5^2-3^2)

=(25-9)

=16

It means (a+b)(a-b)=(a^2-b^2)
