(3x² + xy – 2y²)(x + 2y)​

3x^3+7x^2y−4y^3

Step-by-step explanation:

(3x^2+xy+−2y^2)(x+2y)

=(3x^2)(x)+(3x^2)(2y)+(xy)(x)+(xy)(2y)+(−2y^2)(x)+(−2y^2)(2y)

=3x^3+6x^2y+x2y+2xy^−2xy^2−4y^3

=3x^3+7x^2y−4y^3

Hello This Is ꧁☆•[ҎƦƟ]ҎȽɅȲȄƦ•☆꧂

Step-by-step explanation:

The Answer Is

3x² + x

y - 2y²

So,

3x³ And 2y

3x³ + x = 3x⁴

2y² + 2y = 2y⁴
