hello Eddie:) i have a question for you. why is (a+b)^2 equal to a^2+2ab+b^2 ?

[@sharoonaftab8894]

learn pascal's triangle and then move on to binomial theorem( The main thing) there you have it.

[@mrWade101]

(a+b)^2 = (a+b)(a+b) = a*a + a*b + b*a + b*b = a^2 + 2ab + b^2 Also, as previous commenter said, learn pascals triangle
