Your Enquiry:-
(a+b)^2 = a^2 + 2ab + b^2,(a + b)² = a² + 2ab + b²,(a-b)2 = a2 - 2ab + b2,a+b whole square explained,why (a-b)2 = a2 - 2ab + b2,( a-b )² = a²+ b² - 2ab,(a+b)2 = a2 +2ab + b2,(a+b)2 = a2 +2ab + b2 but why?,( a+b )² = a²+b²+2ab,proof that (a+b)2 = a2 +2ab + b2,maths identity (a-b)2 =a2 - 2ab + b2,geometrical proof of (a+b)2 = a2 +2ab + b2,(a-b)^2=a^2+b^2-2ab,(a+b)^2=a^2+b^2+2ab,(a-b)x+(a+b)y=a^2-2ab-b^2,expansion of (a+b)^2,(a+b)(x+y)=a^2+b^2
