Question

Plz give full solution

Factorise:
$ab(x { }^{2} + y {}^{2}) - xy(a {}^{2} + b {}^{2})$
Answer is:
$(ax - by)(bx - ay)$
Plz answer only if you know the complete solution

Answer 1

$\colour{Pink}{ANSWER}$

$\boxed{FACTORISE}$

$ab(x^2 + y^2) - xy(a^2 + b^2)$

Multiplying ab with $(x^2 + y^2).$
Multiplying xy with $(a^2 + b^2).$

$abx^2 + aby^2 - a^2xy - b^2xy$

Now ,

$(abx^2 - a^2xy) - (b^2xy + aby^2)$

Taking ax common from first group and taking by common from second group.

$ax(bx - ay) - by(bx - ay)$

$(ax - by) (bx - ay)..$
