Question

(ii) (2a2 - 2b2) - (a2-b2) step by step​

Answer 1

Let's simplify step-by-step.

2a^2−2b^2−(a^2−b^2)

Distribute the Negative Sign:

=2a^2−2b^2+−1(a^2−b^2)

=2a^2+−2b^2+−1a^2+−1(−b^2)

=2a^2+−2b^2+−a^2+b^2

Combine Like Terms:

=2a^2+−2b^2+−a^2+b^2

=(2a^2+−a^2)+(−2b^2+b^2)

=a^2+−b^2

Answer:

=a^2−b^2
