Question

please factorise
ab(x²+y²)-xy(a²+b²)

Answer 1

ab(x2+y2)-xy(a2+b2)
abx2+aby2-a2xy-b2xy
abx2-a2xy-b2xy+aby2
ax(bx-ay)-by(bx-ay)
(bx-ay)(ax-by)  Answer

Answer 2

Here's your answer!!

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

$ab {x}^{2} + ab {y}^{2} - xy {a}^{2} - xy {b}^{2}$

$ab {x}^{2} - xy {a}^{2} + ab {y}^{2} - xy {b}^{2}$

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

$ax(xb - ay) - by(xb - ay)$

$(ax - by)(xb - ay)$
