This might sound a bit dumb but am really stuck :L
i need help to answer a question and i need someone to explain to me how to do it
Multiply out the brackets and collect the terms.
(2y3)(ysqaured + 4y 1)

Multiply the stuff in the second set of parentheses by 2y to obtain:
y^2*2y + 4y*2y 1*2y = 2y^3+8y2y
Then multiply the same stuff by 3 as I did above, and collect terms.
