Factorise 121p² - q²?

121p² - q²
=Factor by squaring.
=(11q-q)(11q+q)

**You could still extract this one:

=2q(11-1)(11+1)

**But idk if my professor was joking.

here is answer note please

( 11p+q)*(11p-q)

(11p-q)(11p+q)

(11 p - q) (11 p + q)

a^2 - b^2 = (a + b)(a - b)

121p^2 - q^2
= (11p)^2 - q^2
= (11p + q)(11p - q)

(11p+q)(11p-q)

ladies and gentlemen the answer is this (yahoooooooo)

( 11p+q)*(11p-q)


i hope that helps

(11p+q)(11p-q)

11(11p^2-q^2)

how did you do that ''squared'' sign?

edit:I think I did it wrong..
