Looking at the choices i believe you need a g in your question. If it is 4g+2 Then you factor out at 2 to get 2(2g+1) choice a If it 4+2g then you also factor out a 2 but this time get 2(2+g) choice b Depending on what the question actually is those would be the answers
Sorry for the hand writing. But you want to factor out a 4y^2 which will result in (9y^2-1). Then you will factor out the equation in parentheses to (3y-1)(3y+1). Don’t forget to put the 4y^2 out front!
