b(a-x)
Factorising -x2 + 7x + 18: (a - x)(x + b) = -x2 + (b - a)x + ab so ab = 18, b - a = 7 giving a = 2, b = 9: (2 - x)(x + 9)
x-ab=0 x=ab
ab(ab) =2ab
There are 48 possibilities where 2 of 5 items must be adjacent.If you have 5 items, and they can be arranged in any order, there are 1205 x 4 x 3 x 2 ways to arrange them, for example ABCDE, ABCED, and so forth.However, if any two need to be placed next to each other, the number of variations is reduced to [4 x 3 x 2] x2 (=48), where there are only 4 separate "units" arranged, but the double-unit can appear with either of the pair first.For example, if A and B must be together, you have 24 possibilities:(AB)CDE(AB)CED(AB)DCE(AB)DEC(AB)EDC(AB)ECDC(AB)DEC(AB)EDD(AB)CED(AB)ECE(AB)CDE(AB)DCCD(AB)EDC(AB)ECE(AB)DEC(AB)DDE(AB)CED(AB)CCDE(AB)CED(AB)DEC(AB)DCE(AB)EDC(AB)ECD(AB)and another 24 where (AB) is replaced by (BA).
B2 for B = 9.
b(a-x)
ab(a - b)
30 + ab + 6b + 5a = 5(a+6) + b(a+6) = (b+5)(a+6)
Too bad that's not a^2 - ab - 42b^2 That factors to (a + 6b)(a - 7b)
The sum of two cubes can be factored as below.a3 + b3 = (a + b)(a2 - ab + b2)
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
Sum and difference of two cubes is factored this way : a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
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
