(a-b)2 = a2 _ 2ab+b2
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
a square minus b square
the entire quadratic formula is x is equal to negative b plus or minus the square root b squared minus four(4) a c all over two(2) a (divided by 2)you may have trouble remembering this formula but you can fit it to the tune of pop goes the weasle.here ya go
(a + b + c) 3 = a3 + b3+ c3+ 3a2b + 3a2c + 3ab2 + 3ac2 + 3b2c + 3bc2 + 6abc
'a' minus 'b' whole cube is equal to 'a cube' minus 'b cube' minus (3 a square b ) plus (3 a b square) . .. .....thanks
(a+b)cube = a cube + b cube + 3a square b + 3ab square
(a-b)2 = a2 _ 2ab+b2
(a3-b3) = (a-b) (a2+ab+b2)
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
a square minus b square
Acube -bcube
52500-a = b
a3 + b3 + c3 + 2(a2)b + 2(b2)c + 2(a2)c + 2ab2 + 2(c2)b +abc
(a + b)3 = a3 + 3a2b + 3ab2 + b3
v=b/h/w=area
(a - b)^3 = a^3 - 3a^2b + 3ab^2 - b^3
