Factoring t2+14t+24t^2 + 14t + 24

Factor t2+14t+24t^2 + 14t + 24 by applying the trinomial factoring strategy. Because the variable is tt, each binomial factor begins with tt.

Step 1 — Set up two binomials with first terms tt: (t)(t)(t\quad)(t\quad).

Step 2 — Find two numbers that multiply to 2424 and add to 1414. List the factor pairs of 2424 and check their sums:

  • 11, 2424 (sum is 2525)
  • 22, 1212 (sum is 1414) ✓
  • 33, 88 (sum is 1111)
  • 44, 66 (sum is 1010)

The pair 22 and 1212 works because their product is 2424 and their sum is 1414.

Step 3 — Use 22 and 1212 as the last terms of the binomials: (t+2)(t+12)(t + 2)(t + 12).

Step 4 — Check by multiplying: (t+2)(t+12)=t2+12t+2t+24=t2+14t+24(t + 2)(t + 12) = t^2 + 12t + 2t + 24 = t^2 + 14t + 24 ✓.

The factored form is (t+2)(t+12)(t + 2)(t + 12).
