a square minus b square
(a+b)(a-b)
(a + b + c)3 = a3 + b3 + c3 + 3(a2b + ab2 + b2c + bc2 + ca2 + ac2) + 6abc
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
Using the quadratic formula-- ((negative b plus or minus the square root of b squared minus 4ac) divided by (2a)) you'll want to google that so you can see it in numerical form. a, b, and c are the coefficiants of your three terms ( 2 is a, -5 is b, and 2 is c) The answer is (x-2)(2x-1).
'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 square minus b square
a2+b2+c2-2ab+2bc-2ca
negative b plus or minus the square root of b minus 4 times ac all over 2 a
negative b plus or minus the square root of b squared minus 4AC all over 2 A
(a+b)cube = a cube + b cube + 3a square b + 3ab square
(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)(a-b)
midpoint: (x1+x2/2 , y1+y2/2) quadratic: -b plus or minus square root b squared minus 4ac divided by 2a
x is equal to negative b plus or minus the square root of b squared minus 4 times "a" times "c" all over 2 times "a"
52500-a = b
(a + b + c)3 = a3 + b3 + c3 + 3(a2b + ab2 + b2c + bc2 + ca2 + ac2) + 6abc
