Just expand each product, and combine like terms.
"Expanding" is sometimes called "FOIL"; you will multiply each term of the first factor by each term of the second.
Give it a try, show us your work, and we can help you improve it if necessary.

Do you understand that it is not a good idea to call a mathematics problem "non-sense" when you are asking mathematicians and mathematics students for help?
\(\displaystyle (2x^2y+ 3y^2)(1+ x)= 2x^2y(1+ x)+ 3y^2(1+ x)= 2x^2y(1)+ 2x^2y(x)+ 3y^2(1)+ 3y^2(x)\). .......................edited
