(a+b)cube = a cube + b cube + 3a square b + 3ab square
a square plus 2ab plus b 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
X2+5x-6. a=1, b=5, and c=-6 The formula is: -b plus or minus the square root of b squared minus 4ac all over 2a. -b+square root of b2-4ac ---- 2a -5 plus or minus the square root of 5 squared minus 4(1)(-6) -5 plus or minus the square root of 25-4(-6) -5 plus or minus the square root of 25+24 -5 plus or minus the square root of 49 -5 plus or minus 7 Here is where you split into two different answers: Number 1: -5 plus 7= 2 Number 2: -5 minus 7= -12 Your answer is X=2, -12
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
a square minus b square
It is a^2 + b^2, or a*a + b*b.
(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 square plus 2ab plus b 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
negative b plus or minus the square root of b minus 4 times ac all over 2 a
33
negative b plus or minus the square root of b squared minus 4AC all over 2 A
C Square
it's the bit in the square root sqrt of (b squared minus 4ac) when a,b and c are the values belonging to the equation ax(sqared) plus bx plus c
6a square plus b square
