t2+30t +200 a=1, c=200 ac = 200. Factor pairs of 200 are
1, 200 2, 100 4, 50 5, 40 8, 25 10, 20
We see that 10+20 =30, replace 30t with 10t +20 t.
t2 +10t +20t+200 Factor by grouping.
t(t+10) +20(t+10) The common binomial factor is (t+10)
(t+10)(t+20) It is easy to check the factoring result is correct by multiplying back together.
