Answer 1

Answer:

Option A) x3 + x2y,+ 3xy - 2xy2 + 6y2

Step-by-step explanation:

Lets try to solve it by applying distributive property, this is, multiplying term by term:

(x + 2y)(x2 - xy + 3y) = x*x^2 + x*(-xy) +x*3y + 2y*x2 + 2y*(-xy) +2y*3y

Operating with the terms:

(x + 2y)(x2 - xy + 3y) = x3 - (x^2)y + 3xy + 2y(x^2) - 2x(y^2) + 6(y^2)

This is equal to option A.

Another way of noticing this was the correct answer is that A is the only one with a term of x3, with was evident to be here as we have x multiplying x3.
