Identify Coefficients: Identify the coefficients of the quadratic expression.The quadratic expression is in the form of am2+bm+c. For the expression 2m2+13m+11, we have:a=2, b=13, and c=11.
Find Multiplying Numbers: Find two numbers that multiply to ac (a times c) and add up to b. We need to find two numbers that multiply to 2×11=22 and add up to 13.
Determine Numbers: Determine the two numbers that meet the criteria.The numbers 2 and 11 multiply to 22 and add up to 13.
Rewrite Middle Term: Rewrite the middle term of the quadratic expression using the two numbers found.The expression 2m2+13m+11 can be rewritten by splitting the middle term into 2m and 11m:2m2+2m+11m+11.
Factor by Grouping: Factor by grouping.Group the terms to factor out common factors:(2m2+2m)+(11m+11).
Factor Common Factors: Factor out the common factors from each group.From the first group, factor out 2m:2m(m+1).From the second group, factor out 11:11(m+1).
Write Factored Form: Write the factored form of the expression.Since both groups contain the factor (m+1), we can factor it out:(2m+2)(m+1).
