(3z+1)(4z+2) simplify
Lorico [155]

You can FOIL (First, Outside, Inside, Last)

(3z+1)(4z+2)

First

(3z+1)(4z+2)

3z * 4z

12z^{2}

Outside

(3z+1)(4z+2)

3z * 2

6z

Inside

(3z+1)(4z+2)

4z * 1

4z

Last

(3z+1)(4z+2)

2*1

2

Combine all the products of FOIL together

12z^{2} + 6z + 4z + 2

Combine like terms

12z^{2} + 10z + 2

Hope this helped!
