Question

which graph represents the solution set for the inequality 2x^2+2x-15<-x+5

Answer 1

Have a graphic?

Answer 2

I can tell you that it will be everything within the curve that is below the line y=-x+5.

Answer 3

its on a number line ._.

Answer 4

Oh jeez...

Answer 5

Give me a minute.

Answer 6

lol yea my thoughts exactly, I'm not sure where to start.

Answer 7

Ultimately you have to solve for x. It won't be pretty.

Answer 8

Would add the -x to the other side and add 15 to 5?

Answer 9

Yeah, this is what I have so far:
\[x(2x+3)<20\]

Answer 10

oh wait the solution has to be equal to 0 first then factored

Answer 11

poo on that. Take what I had and test it against two large numbers (one very positive and one very negative) and two small numbers (one slightly positive and one slightly negative). I found the answer to be B.

Answer 12

I found the same thing as you; I plugged in 3 and -5.
x=-4
x= 2.5
