Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 6x2+7x+2, which is in the form ax2+bx+c.a=6, b=7, c=2
Find numbers for multiplication: Find two numbers that multiply to a∗c (6∗2=12) and add up to b (7).The numbers that satisfy these conditions are 3 and 4, since 3∗4=12 and 3+4=7.
Rewrite middle term: Rewrite the middle term 7x using the two numbers found in the previous step, splitting it into two terms 3x and 4x. The expression becomes 6x2+3x+4x+2.
Factor by grouping: Factor by grouping. Group the first two terms and the last two terms.(6x2+3x)+(4x+2)
Factor out common factor: Factor out the greatest common factor from each group. 3x(2x+1)+2(2x+1)
Factor out common factor: Factor out the greatest common factor from each group.3x(2x+1)+2(2x+1)Since both groups contain the common factor (2x+1), factor this out.(3x+2)(2x+1)
