Solution for X (ab2)=100 equation Simplifying X (a b 2) = 100 Reorder the terms X (2 a b) = 100 Remove parenthesis around (2 a b) X 2 a b = 100 Reorder the terms 2 X a b = 100 Solving 2 X a b = 100 Solving for variable 'X'And that can be produced by the difference of squares formula (ab) (a−b) = a 2 − b 2 Like this ("a" is 2x, and "b" is 3) (2x3) (2x−3) = (2x) 2 − (3) 2 = 4x 2 − 9 So the answer is that we can multiply (2x3) and (2x−3) to get 4x2 − 9For a square b square watch http//youtube/24gWbMSEVVwLearn how a minus b whole square can be explained using geometrical drawingsFor more such videos v

If a/b =2 then what will be 4b/a Look at the equation, a/b=2 so therefore a = 2b Now that we know the value of a, that is, 2b, In this equation, 4b/a, All we have to do is substitute the values of a (2b) since a = 2b, then, 4b/2b By normal division, you'll get 2 as the answer(a−b) 2 = a 2 − 2ab b 2 If you want to see why, then look at how the (a−b) 2 square is equal to the big a 2 square minus the other rectangles (a−b) 2 = a 2 − 2b(a−b) − b 2When you square a binomial, you multiply it by itself (a b)^2 = (a b) (a b) = a (a) a (b) b (a) b (b) {used foil method} = a^2 ab ab b^2 {multiplied through} = a^2 2ab b^2 {combined like terms} (a b)^2 = (a b) (a b) = a (a) a (b) b (a) b (b) {used foil method}
