Question 153037: Completely factor the following: r(s) = 2s^2 + st � 2s + t
@ Normally, this would be solved by the �factor by grouping� method. However, this does not work here due to the last term being added, not subtracted. See a. r(s) = 2(s + t)(s � 1)
b. r(s) = (2s + t)(s � 1)
c. This cannot be factored; it�s prime
d. None of the above

r(s)=2s^2+st�2s+t
r(s)=2s^2-2s+st+t
r(s)=2s(s-1)+t(s+1)
answer d) none of the above.
