Question

factorise a b bracket X square + Y square bracket close - xy bracket open a square + b square bracket close

Answer 1

ab (x^2 + y^2) - xy (a^2 +b^2)
abx^2 +aby^2 - a^2xy - b^2xy
abx^2- a^2xy - b^2xy+aby^2
ax ( bx -ay) - by (bx-ay)
(ax-by) (bx-ay).


Hope that helps.

Answer 2

ab(x²+y²) + xy(a²+b²)
abx²+aby²+xya²+xyb²
abx²+xya²+aby²+xyb²
ax(bx+ay) + by(ay+bx)
(ax+by)(ay+bx)
