Full solution

Q. Factor.\newline2t2+13t+112t^{2}+13t+11
  1. Identify coefficients: Identify the coefficients aa, bb, and cc in the quadratic expression 2t2+13t+112t^2 + 13t + 11 by comparing it to the standard form at2+bt+cat^2 + bt + c.a=2a = 2b=13b = 13c=11c = 11
  2. Find two numbers: Find two numbers that multiply to aca*c (which is 211=222*11 = 22) and add up to bb (which is 1313).\newlineThe two numbers that satisfy these conditions are 1111 and 22 because:\newline11×2=2211 \times 2 = 22\newline11+2=1311 + 2 = 13
  3. Rewrite middle term: Write the middle term 13t13t as the sum of two terms using the numbers found in the previous step.2t2+13t+112t^2 + 13t + 11 can be rewritten as:2t2+11t+2t+112t^2 + 11t + 2t + 11
  4. Factor by grouping: Factor by grouping. Group the first two terms and the last two terms.\newline(2t2+11t)+(2t+11)(2t^2 + 11t) + (2t + 11)
  5. Factor out common factor: Factor out the greatest common factor from each group.\newlinet(2t+11)+1(2t+11)t(2t + 11) + 1(2t + 11)
  6. Final factorization: Since both groups contain the common factor (2t+11)(2t + 11), factor this out.(2t+11)(t+1)(2t + 11)(t + 1)
