(a+b)cube = a cube + b cube + 3a square b + 3ab square
'a' minus 'b' whole cube is equal to 'a cube' minus 'b cube' minus (3 a square b ) plus (3 a b square) . .. .....thanks
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
(a + b)3 = a3 + 3a2b + 3ab2 + b3
If you mean (a-b+c)^2, then... a^2 - ab + ac - ab + b^2 - bc + ac - bc + c^2 = a^2 + b^2 + c^2 - 2ab + 2ac - 2bc.
(A+B)2 = (A+B).(A+B) =A2+AB+BA+B2 =A2+2AB+ B2 So the Answer is A + B the whole square is equal to A square plus 2AB plus B square. Avinash.
(a+b)cube = a cube + b cube + 3a square b + 3ab square
(a+b+c)²=a²+b²+c²+ 2ab+2bc+2ac
'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-c)2 = a2 + b2 +c2 +2ab - 2bc - 2ac
(a+b)^2=a^2+b^2+2ab it should read "the quanitity "a plus b" squared equals a squared plus b squared plus two a times b" See related link below for a picture that shows it graphically.
It is a^2 + b^2, or a*a + b*b.
a square minus b square
C Square
6a square plus b square
Yes.
(a+b+c) 2=a2+ab+ac+ba+b2+bc+ca+cb+c2a2+b2+c2+2ab+2bc+2ca [ ANSWER!]
