Question

Am I correct here with 1.B and 2. C

Answer 1

yes

Answer 2

For the first question, all the answer choices have the same real root -3.
the first 3 choices show 2 complex roots.
remember, if you have complex roots (for a real polynomial.. which you have here)
the roots *must be* complex conjugates. only choice B shows a complex conjugate pair.

so either B or D. to rule out D, test one of the values: 2.
2^3 -5 * 2^2- 4*2 + 60 = 40 which is not 0. so that leaves only B as an answer

Answer 3

awesome, I got that one :)

Answer 4

for the second question, you want the 4 x values where the red and blue curves meet.
they do not intersect at x=0

Answer 5

alright i got it wrong then

Answer 6

can you pick the correct choice?

Answer 7

so if yon' wont the 4x values then..... :

Answer 8

right

Answer 9

the circles are the (x,y) points where the curves cross. the solution is just the x value of each pair.
