6v(2v+3) 1) 6v*2v=12v^2 2) 6v*3=18v 3)put them together like this: 12v^2+18v this is your answer. If the sign had been a minus in front of the 3 your answer would have been a subtraction equation.

[latex]6v(2v+3)=6v\cdot2v+6v\cdot3=12v^2+18v[/latex] [latex]6v\cdot2v=6\cdot2\cdot v\cdot v=12\cdot v^2=12v^2\\\\6v\cdot3=6\cdot3\cdot v=18\cdot v=18v[/latex]
