This is the problem: Consider the Boolean expression (X+Y)(+Z)(Y+Z). Obtain the sum-of-products. Use a K-map to obtain its minimal sum-of-products. The image below is how far I got. Every K-Map exercise I've done so far has always had minterms with the same number of variables, but I came up with this SOP that has 2 and 3 variable minterms; so I don't know if I did something wrong in obtaining the SOP or how I'm supposed to enter the minterms in the K-Map here.

This is the problem:

Consider the Boolean expression (X+Y)(+Z)(Y+Z).

    1. Obtain the sum-of-products.
    2. Use a K-map to obtain its minimal sum-of-products.

The image below is how far I got. Every K-Map exercise I've done so far has always had minterms with the same number of variables, but I came up with this SOP that has 2 and 3 variable minterms; so I don't know if I did something wrong in obtaining the SOP or how I'm supposed to enter the minterms in the K-Map here.
