Multiply the polynomial

Question

(X²-2y)(x²+2y)

Answer 1

Begin by multiplying x^2 by x^2 and 2y. This will give you: x^4+2(x^2)y

Then, multiply -2y by x^2 and 2y. This will give you: -2(x^2)y-4y^2

Now, combining your results: x^4+2(x^2)y-2(x^2)y-4y^2

Lastly, simplify the expression to get the final answer: x^4-4y^2
