Factoring q2+10q+24q^2 + 10q + 24

Factor q2+10q+24q^2 + 10q + 24 by applying the trinomial factoring strategy. Because the variable is qq, each binomial factor begins with qq.

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

Step 2 — Find two numbers that multiply to 2424 and add to 1010. 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 44 and 66 works because their product is 2424 and their sum is 1010.

Step 3 — Use 44 and 66 as the last terms of the binomials: (q+4)(q+6)(q + 4)(q + 6).

Step 4 — Check by multiplying: (q+4)(q+6)=q2+6q+4q+24=q2+10q+24(q + 4)(q + 6) = q^2 + 6q + 4q + 24 = q^2 + 10q + 24 ✓.

The factored form is (q+4)(q+6)(q + 4)(q + 6).
