Someone help me understand this step by step please.

Step-by-step explanation:

(s*t)(x) = (x+2)(3x+2)

Using the Associative Property of Multiplication, we get

(s*t)(x) = 3x²+2x+6x+4 = 3x²+8x+4

For (s+t)(x), we just add the two to get 4x+4

For (s-t)(x), we subtract t from s to get -2x. Plugging -1 in for x, we get -2(-1)=2
