Answer:3x^2+3x

Explanation:

3x=3x+0

(3x+0)(x+1)

Multiply the numbers on the left of the plus signs within each parentheses.

3x*x= 3x^2

Then the left of the plus sign in the 1st set by the right in the 2nd set.

3x*1= 3x

Then right if first by left of second

0*x=0

Right of 1st and right of 2nd.

0*1=0

Now add each piece.

3x^2+3x+0x+0

Simplify

3x^2+3x
