What does square of binomial mean?
It means you multiply the binomial by itself. Multiplying polynomials requires multiplying every term of the first with every term of the second. For example, (a+b)2 = a2 + ab + ba + b2 = a2 + 2ab + b2.It means you multiply the binomial by itself.

How do you expand A-B times A squared AB-B squared?
The question is a little unclear. If you mean: (A - B) x A2, then the answer is: A3 - (B x A2) (or, more simply, A3-BA2) If you mean: ((A - B) x A)2, then the answer is: (A2 - AB)2 which becomes A4 - 2A3B + A2B2

If I give you a piece of paper and say prove a b 2 a2 b2 2ab How will you do that with out any writing device?
Prove (a+b)2 = a2 +b2 + 2ab It can be done by folding the paper. First fold one corner over and cut off excess to get a square piece of paper. Flatten out again. Fold a corner over most but not all of the way. The length of folded side is a. The rest of the side is b. The folded over area is a2 The unfolded strips along the sides are ab. There are 2 of them = 2ab The unfolded square remaining is b2 Therefore the total square (a+b)2 = a2 + 2ab + b2
How do you factor the expression x cubed minus 8?
(x3 - 8) is factored thus: (x - 2)(x2 + 2x + 4) The easiest way to do this is to remember the formula: (a3 - b3) = (a - b)(a2 + ab + b2)
What is b squared plus ab minus two minus two b squared plus two ab?
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
Why does b times ab equal ab squared and not equal ab plus b squared?
b*ab = ab2 Suppose b*ab = ab + b2. Assume a and b are non-zero integers. Then ab2 = ab + b2 b = 1 + b/a would have to be true for all b. Counter-example: b = 2; a = 3 b(ab) = 2(3)(2) = 12 = ab2 = (4)(3) ab + b2 = (2)(3) + (2) = 10 but 10 does not = 12. Contradiction. So it cannot be the case that b = 1 + b/a is true for all b and, therefore, b*ab does not = ab + b2
Factor ab - 2ac plus b2 - 2bc?
ab-2ac+b^2-2bc
What is sqare of a-b?
(a-b)2 = (a-b)(a-b). You have to multiply each term in the left monomial by each term in the right monomial: a2 - ab - ab + b2 = a2 - 2ab + b2.
What is wrong with the proof below that two equals one?
Proof that 2 equals 1.Given:a = 1b = 1Proof:a = ba2 = ab Multiply by aa2 - b2 = ab - b2 Subtract b2(a + b)(a - b) = b(a - b) Factor(a + b)(a - b)/(a - b) = b(a - b)/(a - b) Divide by (a - b)a + b = b2 = 1AnswerThe problem arises when you begin dividing by zero, in this case (a-b). It is easy to be distracted by the algebra, (a-b), and miss the fact that since a is equal to b, then (a-b) is equal to zero. As you probably know division by zero isn't allowed in mathematics.
Find the gcf of 27 ab and 81 b 2?

2A3 plus 3B2 6AB If 10 moles of A3 are reacted with excess B2 how many moles of AB will be produced?
For every 2 moles of A3, 3 moles of B2 react to form 6 moles of AB. Since we have 10 moles of A3, we need to double the moles of B2 reacting, which would be 15 moles of B2 to fully react with the 10 moles of A3. This would produce 30 moles of AB.
If 10 moles of A3 are reacted with excess B2 how many moles of AB will be produced 2A3 plus 3B2 6AB?
From the balanced equation, 2 moles of A3 react with 3 moles of B2 to produce 6 moles of AB. Therefore, if 10 moles of A3 are reacted, the ratio of moles of AB produced would be (10 moles A3 / 2 moles A3) * 6 moles AB = 30 moles AB.
Evaluate the expression b2-7b-6 when b equals -4?
