(a+b)2=a2+2ab+b2
(a-b)2=a2-2ab+b2
(a+b+c)2=a2+b2+c2+2ab+2bc+2ca
(a+b)3=a3+b3+3ab(a+b)
(a-b)3=a3-b3-3ab(a-b)
(x+a)(x+b)=x2+x(a+b)+ab
( wherever i have put 2 is square except 2ab,2bc,2ca only in1,2,3)
( wherever i have put 3 is qube except 3ab in 4 and 5)
( wherever i have put 2 is square in 6 )
these are the formulaes taught in 8th....
