The answer is: 56xy³
_______________________________
Explanation:
_______________________________
Find the "like terms"; which are:
_______________________________
"4y" and "2y²"
_______________________________
The remaining term is: "7x".
_____________________________________
The problem is a "multiplication problem" :
___________________________________________
7x 4y 2y² ; so start by multiplying the "like terms" :
___________________________________________
4y 2y² = 8y³
____________________________________________
Then the remaining term is "7x";
so, multiply that by our obtained value: "8y³ " :
_____________________________________________
7x 8y³ = 56xy³ ; which is our answer:
