Identify trinomial: Identify the trinomial to be factored, which is 2x2+7x+5.
Find suitable numbers: Look for two numbers that multiply to give the product of the coefficient of x2 term (which is 2) and the constant term (which is 5), and add up to the coefficient of the x term (which is 7).
Determine numbers: The two numbers that fit the criteria from Step 2 are 5 and 2, since (5)(2)=10 and 5+2=7.
Rewrite middle term: Write the middle term 7x as the sum of two terms using the numbers found in Step 3: 5x+2x.2x2+7x+5 becomes 2x2+5x+2x+5.
Factor by grouping: Factor by grouping. Group the first two terms together and the last two terms together: (2x2+5x)+(2x+5).
Factor out common factor: Factor out the greatest common factor from each group. From the first group, factor out x, and from the second group, factor out 1.x(2x+5)+1(2x+5).
Final factored form: Since both groups contain the common factor (2x+5), factor this out to get the final factored form.(2x+5)(x+1).
