Question

factorise 16(5x+3y)^2-24(5x+3y)​

Answer 1

$16 ({5x + 3y)}^{2} - 24(5x + 3y) \\ 16(25 {x}^{2} + 9 {y}^{2} ) - 120x + 72y \\ 400 {x}^{2} + 144 {y}^{2} - 120x + 72y \\ 400 {x}^{2} - 120x + 144 {y}^{2} + 72y \\ 20x(20x - 6) + 72y(2y + 1) \\ (20x + 72y)(20x - 6)(2y + 1) \\ 4(5x + 18y)2(10x - 3)1(2y + 1) \\ (4 + 2 + 1)(5x + 18y)(2y + 1) \\ 7(5x + 18y)(2y + 1)$
