Hello!
In this exercise we have a division (or fraction). To solve it, first we can simplify some values, look:
[tex]\frac{-15w^2+10w}{5w}[/tex]Both numbers in the numerator are multiples of 5w, so we can cancel it:
[tex]\frac{-\cancel{15w}^2+\cancel{10w}}{\cancel{5w}}=\frac{-3w+2}{1}=\boxed{-3w+2}[/tex]-3w +2.
