Question

Factor completely (a-3)^(2) - (4b)^(2)

Answer 1

a lot like the last one
it is the difference of two squares
\[x^2-y^2=(x+y)(x-y)\] use \(x=(a-3)\) and \(y=2b\)

Answer 2

\((a-3)^{2} - (4b)^2\)
\[=[(a-3)+(4b)][(a-3)-(4b)]\]

Answer 3

ooops i made a mistake , it is \(4b)^2\) not \((4b^2\) so go with @TheViper answer

Answer 4

oh lol sir :)
