-y^2(3y-5)=color(green)(-3y^3 + 5y^2y2(3y5)=3y3+5y2

Explanation:

color(blue)(a*(b-c) = a*b - a*ca(bc)=abac ---- (Distributive Property)

Applying it to the given expression,
-y^2(3y-5) = -y^2(3y) - (-y^2)(5)y2(3y5)=y2(3y)(y2)(5)

We also know that color(blue)(a^m*a^n = a^(m+n)aman=am+n

Hence the expression will be:

-3y^(2+1) + 5y^23y2+1+5y2

=color(green)(-3y^3 + 5y^2=3y3+5y2
