Question

Expand (x²y - xy²)² by using suitable identities *
​

Answer 1

Answer:

(x²y - xy²)²

Let x²y =a

Let xy² =b

(a - b)^2

a^2+b^2-2ab

(x^2y)^2+(xy^2)^2-2((x^2y)(xy^2))

I think the answer is correct and help u

Answer 2

Answer:

x⁴y²- x²y⁴

Step-by-step explanation:

(x²y-xy²)(x²y-xy²)

x²y(x²y-xy²)+ xy²(x²y-xy²)

x⁴y⁴ - x³y³+ x³y³ -x²y⁴

= x⁴y² - x²y⁴
