Question

factorize the following using identities and midterm breaking where applicable. a.81-x2y2 b.1/u2-v2 c.a2b2-144 d.103 square 2 2 in every Q is square

Answer 1

a) 81-x²y²

by a²-b²=(a-b)(a+b)

therefore, 81-x²y²= (9-xy) (9+xy)

b) 1 = [ 1 ] [ 1 ] ...by a²-b² = (a-b)(a+b)

u²-v² u-v u+v

c) a²b²-144

by a²-b²= (a-b) (a+b)

therefore,a²b²-144= (ab-12) (ab+12)

I did not get the last one, otherwise, I have tried to solve...

I hope it helps!!
