Question

using identities find (ab +x²) (ab -x²)
​

Answer 1

Answer:

Q) (ab+x^2) (ab-x^2)

= using, (p+q) (p-q)= (p)^2-(q)^2

=(ab+x^2) (ab-x^2) = (ab)^2 - (x^2)^2

Therefore, (ab)^2-(x^2)^2

Here is your answer.....hope it helps!

Answer 2

Answer:

Given,

=(ab+x^2)(ab-x^2)

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

=a^2b^2-x^4
