Question

pls..help me how to solve it..

Answer 1

\[9x ^{2}y ^{2}-16w ^{2}\]

Answer 2

there is nothing to solve here. there is no equation, just an expression

Answer 3

perhaps the instructions are "factor"?

Answer 4

difference of two square
\[a^2-b^2=(a+b)(a-b)\] here you have
\[a=3xy,b=4w\] so should get
\[(3xy+4w)(3xy-4w)\]

Answer 5

Factoring Binomial
