a square minus b square
(a-b)2 = a2 _ 2ab+b2
It is "a squared minus eighteen b".
B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
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 square minus 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
(a-b)2 = a2 _ 2ab+b2
a2+b2+c2-2ab+2bc-2ca
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
x equals negative b plus or minus the square root of b squared minus 4bc over 2a
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
Remember to factor out the GCF of the coefficients if there is one. A perfect square binomial will always follow the pattern a squared plus or minus 2ab plus b squared. If it's plus 2ab, that factors to (a + b)(a + b) If it's minus 2ab, that factors to (a - b)(a - b)
The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
its B
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
