Question

Please answer the question 5 part 1 and 2 using identity (a+b)(a-b)=a^2-b^2

Answer 1

(i) a^4 - 4b^4
(ii) 36x^4 - 49y^4

Please mark brainliest or thanks if it helped :D

Answer 2

Hey mate thank for the question
Hope it helps
5(1) (a2+2b2)(a2-2b2)
By using identitiy (a2+b2)(a2-b2)=a4-b4
=a^4-4b^4
(2)(6x2-7y2)(6x2+7y2)
By using identitiy =(x2-y2)(x2+y2)=x4-y4
=36x^4-49y^2
Hope it helps :)
