Identify Variables: Identify a, b, and c in the quadratic expression 3y2+8y+4 by comparing it with the standard form ax2+bx+c.a=3b=8c=4
Find Two Numbers: Find two numbers that multiply to a∗c (which is 3∗4=12) and add up to b (which is 8).The two numbers that satisfy these conditions are 2 and 6 because:2×6=122+6=8
Rewrite Middle Term: Rewrite the middle term 8y using the two numbers found in the previous step 2 and 6. 3y2+8y+4 can be rewritten as: 3y2+2y+6y+4
Factor by Grouping: Group the terms into two pairs and factor by grouping.Group (3y2+2y) and (6y+4).Factor out the greatest common factor from each group.From (3y2+2y), factor out y:y(3y+2)From (6y+4), factor out 2:2(3y+2)
Final Factored Form: Notice that both groups now have a common factor of 3y+2. Factor out the common factor to get the final factored form: y+23y+2
