hoblos · Answer

you must use the formula

do you know it??

anonymous · Answer

nope

anonymous · Answer

in my school of survival ... no one will going to trust to ... but you self is the one who trust on you

hoblos · Answer

(a-b)^2 = a^2 -2ab +b^2
(a+b)^2 = a^2 +2ab +b^2

(a-b)(a+b) = a^2 - b^2

these formulas you must know when factorizing
