2. If C = 2a^2 - 5 and D = 3 - a, then C - 2D equals
A) 2a^2 + a - 8
B) 2a^2 - a - 8 ***
C) 2a^2 + 2a - 11
D) 2a^2 - a - 11
1. Factor 4t + 2rt + 8st completely.
A) t(2 + r + 4s)
B) t(4 + 2r + 8s)
C) 2t(2 + r + 4s) ***
D) 2(t + rt + 4st)

not B. You want C-2D
A is C-D. B is not even that.
A is C-D. B is not even that.
So the first one is correct right?
NO! I just told you that A = C-D but you want C-2D
C-2D = 2a^2 - 5 - 2(3-a) = 2a^2 - 5 - (6-2a)
C-2D = 2a^2 - 5 - 2(3-a) = 2a^2 - 5 - (6-2a)
By A i meant problem 1, sorry for the confusion
oops. Yes, #1 is correct.
