Question

a2x2-9b2y2 factorisation

Answer 1

${a}^{2} {x}^{2} - 9 {b}^{2} {y}^{2} \\ \\ = {(ax)}^{2} - {(3by)}^{2} \\ \\ = (ax + 3by)(ax - 3by)$

Answer 2

$a^2 x^2 - 9b^2 y^2$

$(ax)^2 - (3by)^2$
___________________

By Formula $a^2- b^2 =(a+b)(a-b)$
_________________________________


$(ax)^2 - (3by)^2$

(ax + 3by) (ax - 3by)


i hope this will help you
