Identify coefficients: Identify the coefficients a, b, and c in the quadratic expression 2t2+13t+11 by comparing it to the standard form at2+bt+c.a=2b=13c=11
Find two numbers: Find two numbers that multiply to a∗c (which is 2∗11=22) and add up to b (which is 13).The two numbers that satisfy these conditions are 11 and 2 because:11×2=2211+2=13
Rewrite middle term: Write the middle term 13t as the sum of two terms using the numbers found in the previous step.2t2+13t+11 can be rewritten as:2t2+11t+2t+11
Factor by grouping: Factor by grouping. Group the first two terms and the last two terms.(2t2+11t)+(2t+11)
Factor out common factor: Factor out the greatest common factor from each group.t(2t+11)+1(2t+11)
Final factorization: Since both groups contain the common factor (2t+11), factor this out.(2t+11)(t+1)
