A)15s2 + 26s + 8

B) x4 – 5x2 – 36 (hint: let a = x2)

C) t2 + 4t – 2

D) 2w2 – w – 4

**Steve**, Tuesday, March 20, 2012 at 10:57amA) You know it will be one of

(5s+a)(3s+b)

(15s+a)(s+b)

where a*b = 8

Looks like 15,1 won't work, so

(3s+4)(5s+2)

wolframalpha will do polynomial factorization, but the only way you'll be ready for a test is to do lots of these. It's just trial and error until you have enough practice to factor by inspection.
