Believe this is correct

Answer:

3z^2 + 4z+1

Step-by-step explanation:

(3z + 1)(z + 1)

we multiply it to get the polynomial

Apply FOIL method to multiply

Multiply 3z with z+1 first

3z *z = 3z^2

3z * 1 = 3z

Now multiply 1 with z+1

1*z= 1z

1*1= 1

Now we write all the terms together

3z^2 + 3z +1z +1

Combine like terms

3z^2 + 4z+1
