How do you find the sum of -5ab plus 7ab plus -9ab plus ab plus -2ab?
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
How do you solve 2ab-3b2-3b plus 2a?
2ab - 3b2 - 3b + 2a does not have a solution, as it is not an equation.
X equals 2ab plus 7 find x if a equals 3 and b equals 5?
42 72
How do you factor a times a cubed plus 2 times a times b plus b squared?
the answer to factorising (a x a3 + 2ab + b2) would be (a4+2ab+b2)
X2 -5kx plus 25 the square of binomial. what is a possible value of k?
k can be 2 or -2. A binomial squared is: (a + b)² = a² + 2ab + b² Given x² - 5kx + 25 = (a + b)² = a² + 2ab + b² we find: a² = x² → a = ±x 2ab = -5kx b² = 25 → b = ±5 If we let a = x, then: 2ab = 2xb = -5kx → 2 × ±5 = -5k → k = ±2 If k = 2 then the binomial is (x - 5)² If k = -2 then the binomial is (x + 5)² To be complete if a = -x, then: If k = 2 then the binomial is (-x + 5)² If k = -2 then the binomial is (-x - 5)² which are the negatives of the binomials being squared.

Find the difference (-2ab-2a-5)-(6ab plus 2)?
4ab - 2a - 7
Show a plus b divided 2 equals 2ab divided by a plus b?
b/2=2ab/+b means112.5
How do you factor fully 'a4 plus 4b4?
(a2+2b2-2ab)(a2+2b2+2ab)
How do you solve 2ab-3b2-3b plus 2a?
2ab - 3b2 - 3b + 2a does not have a solution, as it is not an equation.
What does ab plus ab equals?
Oh, dude, you're hitting me with some math here. Okay, so, like, if you have "ab" plus "ab," you're basically just adding the same thing twice, so it's like adding two apples plus two apples - you end up with four apples. So, "ab" plus "ab" equals "2ab." Math can be weirdly simple sometimes, right?
What is 5ab plus 4a-b-2ab plus 5b?
5ab-2ab+4a-b+5b = 3ab+4a+4b
A plus b the whole square?
a square plus 2ab plus b square
3ab plus 7ab-12ab equals?
-2ab
X equals 2ab plus 7 find x if a equals 3 and b equals 5?

How do you factor a times a cubed plus 2 times a times b plus b squared?
the answer to factorising (a x a3 + 2ab + b2) would be (a4+2ab+b2)
How do you factor perfect square binomial?
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)
