A^2-2ab+B^2 is actually (A+B)^2 AB squared is A^2B^2 or (AB)^2
(a x b)^b =ab x b^2 =ab^3
Factor by grouping. x2y - xyb - abx + ab2 The first two can factor out an xy, so xy(x - b) The second two can factor out a -ab, so -ab(x - b) and we have xy(x - b) - ab(x - b) Since what is inside the parentheses is alike, we can be assured that we have factored correctly and now continue to group: ANS: (x - b)(xy - ab)
a+b(a+B)=ab
You want: abc + ab Factor out the common terms which are "a" and "b" ab ( c + 1 )

A^2-2ab+B^2 is actually (A+B)^2 AB squared is A^2B^2 or (AB)^2
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
No, ab squared is not the same as 2ab. ab squared (ab^2) means multiplying ab by itself, resulting in a^2 * b^2. On the other hand, 2ab means multiplying 2 by a and then by b, resulting in 2ab. These two expressions are not equivalent because ab^2 involves squaring the variable b, while 2ab does not involve squaring any variables.

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
ab x ac = ab - ac
(a-b)^2 doesn't have a numeric value since there are no numbers associated with it, but you can definitely expand it, as it represents a formula, instead of an actual numeric expression.(a-b)(a-b)= a^2-ab-ab+b^2= a^2-2ab+b^2 (which is actually the rule for expanding!)
ab is 26.If abb x 7 = 18ba then a = 2 (if a = 1 then the maximum value of abb is 199, and 7 x 199 = 1393 : if a ≥ 3 then the product would start with a '2' or higher number)The equation now becomes 2bb x 7 = 18b2b is therefore an even number such than 7 x b has a final digit of 2. The only number that satisfies this condition is 6 so that 7 x 6 = 42.a is 2 and b is 6.
