Question

factor 4m^2-n^2

Answer 1

\[\large{(4m^2-n^2)}\]
We can write \(\large{\color{blue}{4m^2}}\) as \(\large{\color{green}{(2n)^2}}\)
therefore we have :
\[\large{\color{grey}{(2n)^2-n^2}}\]

Answer 2

oops sorry I meant 2m^2

Answer 3

\[\large{\color{grey}{(2m)^2-n^2}}\]
\[\large{\color{green}{(2m+n)(2m-n)}}\]
as (a^2-b^2) = (a+b)(a-b)
