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
