Identify trinomial: Identify the trinomial that needs to be factored.The trinomial given is 2x2+17x+30.
Find two 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 30), and add up to the coefficient of the x term (which is 17).We need two numbers that multiply to 2×30=60 and add up to 17.
Find pair of numbers: Find the pair of numbers that meet the criteria from Step 2.The numbers 5 and 12 multiply to 60 (5×12=60) and add up to 17 (5+12=17).
Write middle term: Write the middle term 17x as the sum of two terms using the numbers found in Step 3.17x can be written as 5x+12x.So, the trinomial 2x2+17x+30 can be rewritten as 2x2+5x+12x+30.
Factor by grouping: Factor by grouping.Group the terms into two pairs: (2x2+5x) and (12x+30).
Factor out common factor: Factor out the greatest common factor from each group.From the first group 2x2+5x, we can factor out an x to get x(2x+5).From the second group 12x+30, we can factor out a 6 to get 6(2x+5).
Write final factored form: Write the final factored form using the common binomial factor from both groups.Since both groups contain the binomial (2x+5), the trinomial can be factored as (x+6)(2x+5).
