Answer 2

what do you mean?

Answer 3

there's nothing given if that was your question

Answer 4

do I go ahead and distribute?

Answer 5

how there is (r-1)(2r+3)(r+6), for each of those you go ahead and find the solutions...for example
r-1=0
r=1
and you do that for all of them...once you have those you plug it back in to see your answer

Answer 6

oh i see okay one sec

Answer 7

so 1) r = 1
2) r = -3/2
3) r = -6
right?

Answer 8

correct! so now plug each one of those back into the equation to see which one ends up <0

Answer 9

oka i can take it from there. thank you so much!
