121m^2-144   .....I assume you might want to factor this??

It's just the difference of two squares.

Take the square roots of both terms......and write them twice. Then separate the first pair with a plus and the second pair with a minus......and it's factored !!! So we have

(11m +  12 )     ( 11m  -  12 )  ...........voila !!!!
