Question

factorise (3x - 2y ) Square - 5 ( 3x -2y ) -24​

Answer 1

Answer:

${(3x - 2y)}^{2} - 5(3x - 2y) - 24 \\ \\ using \: {(a - b) }^{2} \\ \\ = {a}^{2} - 2ab + {b}^{2} \\ \\ = ({3x}^{2} - 2 \times 3x \times 2y + {2y}^{2} ) - 5(3x - 2y) - 24 \\ \\ = 9 {x}^{2} - 12xy + 4 {y}^{2} - 15x + 10y - 24$
