I REALLY NEED HELP WITH THIS PLEASE PLEASR PLEASE HELP!!!!!!!!!!!!!!!
@JoannaBlackwelder @DanJS @uri
remember a perfect square has all sides the same length when you factor the thing, it should have one zero value
\[\large x^2+2a*x+a^2=(x+a)*(x+a) = (x+a)^2\]
for the first one is the two last ones???
for example x^2 + 2x + 1 = (x+1)^2 that is one of them
so is the two first ones?
if you see something in the form A*x^2 + B*x + C if you factor into single binomial ( ) ^2, then it is the perfect square... like shown here http://zonalandeducation.com/mmts/miscellaneousMath/perfectSquare/perfectSquare.html
ok
so any quadratic that factors to a single term works, either (x - a)^2 = x^2 - 2ax - a^2 or (x + a)^2 = x^2 + 2ax + a^2
