Question

plz solve the solve the question by cross multiplication

please answer me fast​

Answer 1

Step-by-step explanation:

1. a²x+a²y-b²x-b²y = a²x-aby+abx-aby-b²y

a²x - a²x +a²y- b²x -b²y+b²y =ab(x-y)-aby - b²y

a²y-b²x +b²y=abx-2aby

a²y-b²(x-y) =abx-2aby

2. p²x + pqx +pqy+q²y= pqx- p²y-q²x+p²y+pqy

simplify it you will be getting answer

3. 2a²x- 2aby =a²x +b²x+ a²y+b²x +b²y

simplify it.
