Answer:
Step-by-step explanation:
(x + 2y²)(2x - 2y²)
FOIL
First
x(2x) = 2x²
Outside
x(-2y²) = - 2xy²
Inside
2y²(2x) = 4xy²
Last
2y²(-2y²) = - 4y⁴
combine like terms
2x² + 2xy² - 4y⁴
Answer:
-4y^4 + 2xy^2 + 2x^2
Step-by-step explanation:
(x + 2y^2) (2x - 2y^2)
x(2x) + x(-2y^2) = 2x^2 - 2xy^2
2y^2(2x) + 2y^2(2y^2) = 2xy^2 + 4y^4
2x^2 - 2xy^2 + 4xy^2 - 4y^4
2x^2 + 2xy^2 - 4y^2
or
-4y^4 + 2xy^2 + 2x^2
