Identify a, b, c: Identify a, b, and c in the trinomial 2x2+7x+6. Compare 2x2+7x+6 with ax2+bx+c. a=2b0b1
Find two numbers: Find two numbers whose product is a∗c (2∗6=12) and whose sum is b (7).We need to find two numbers that multiply to 12 and add up to 7.The numbers 3 and 4 satisfy these conditions because:3∗4=123+4=7
Rewrite middle term: Rewrite the middle term 7x using the two numbers found in Step 2.We can express 7x as 3x+4x.So, the trinomial becomes:2x2+3x+4x+6
Factor by grouping: Factor by grouping.Group the terms into two pairs:(2x2+3x)+(4x+6)Factor out the greatest common factor from each pair:x(2x+3)+2(2x+3)
Factor out common binomial: Factor out the common binomial factor.The common binomial factor is (2x+3).The factored form is:(x+2)(2x+3)
