Identify Variables: Identify a, b, and c in the quadratic expression 3w2+8w+4 by comparing it with the standard form ax2+bx+c. a=3 b=8 c=4
Find Multiplying 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=12 and 2+6=8.
Rewrite Middle Term: Rewrite the middle term, 8w, using the two numbers found in the previous step.3w2+8w+4 can be rewritten as 3w2+2w+6w+4.
Factor by Grouping: Factor by grouping. Group the first two terms and the last two terms.(3w2+2w)+(6w+4)
Factor Out Common Factors: Factor out the greatest common factor from each group.From the first group, factor out w: w(3w+2)From the second group, factor out 2: 2(3w+2)
Final Factored Form: Notice that both groups contain the common factor 3w+2. Factor this out.The factored form is w+23w+2.
