Question

Can someone teach me how to multiply this:
(2x + 5y)(3x^2 - 4xy + 2y^2)

Answer 1

$$ \Large (2x + 5y)(3x^2 - 4xy + 2y^2) \\

\Large 2x \cdot 3x^2 + 2x \cdot (-4xy) + 2x \cdot 2y^2 + 5y \cdot 3x^2 +5y \cdot(- 4xy) + 5y \cdot 2y^2 \\

$$

Answer 2

$$ \Large (2x + 5y)(3x^2 - 4xy + 2y^2) \\

\Large = 2x \cdot 3x^2 + 2x \cdot (-4xy) +2x \cdot 2y^2 \\
\Large + 5y \cdot 3x^2 +5y \cdot(- 4xy) + 5y \cdot 2y^2 \\

$$

Answer 3

from there, would I combine like terms?
