Question

factorise 2ab (x square + y square ) + 2xy (a square + b square)​

Answer 1

Answer:

x + 2xy + y – a' + 2ab – 62

(x² + 2xy + y) + (-a² + 2ab – 6')

(x² + 2xy + y²) – (a? – - - 2ab + b2)

x X x y + (y)²) ((a)² 2 x a x b+ (b)²) ((x) + 2 x y + (y)') – ((a)² – 2 x a >

(x + y)² – (a – b)²

Now it is in the format a^2 - b^2. We have to factorise in the format (a + b) (a - b).

(ӕ + у) + (а — б)) (ӕ +у) — (а — и) - - -

(x + y + a – b) (x + y – a + b) -
