When you divided by xab you threw away the root x=ab Just like in the equation t(t1)=t(2t5), if we cancel the t we are losing the root t=0 When you divided by x − a − b you threw away the root x = a b1) (a b)^3 = (a b) (a b) (a b) = (a*a b*a a*b b*b) (a b)A list of the most commonly used algebra formulas Exponents, polynomials, etc A good quickreference list or formula study guide

(a-b)3 formula in maths
(a-b)3 formula in maths-Explanation (a b)3 is the same as (a b)2(a b), so if we write it in this way, it becomes a much easier problem to solve (a b)2 is the same as (a b)(a b), and if we distribute the a and b to both terms, we'll get a2 2ab b2 We now have (a b)(a2 2ab b2)(abc) 3 a 3 b 3 c 3 We can choose three "a"'s for the cube in one way C(3,3)=1, or we can choose an a from the first factor and one from the second and one from the third, being the only way to make a3 The coefficient of the cubes is therefore 1 (It's the same for a, b and c, of course) 3a 2 b3a 2 c Next, we consider the a 2 terms We can choose two a's from 3 factors in C(3,2) ways=3
