your answer is wrong

take it one step at a time.
what is s^3 for s = 1/2?

I need feedback to help you, tina

you substitute s for 1/2

sorry gave you the wrong equation
P(s)=2s^3-2s-1

your answer is still wrong.
take it one step at a time.
what is s^3 for s = 1/2?

1/4

are you sure? s cubed is s times s times s.

its not that complicated
p(s)=2s^3-2s-1
p(1/2)=2(1/2)^3-2(1/2)-1

right, so 2s^3 is 2 times 1/2 times 1/2 times 1/2
what is that equal to?

2/8=1/4

okay good.
what is 2s?

The value of 2s for s = 1/2 is?

2/2=1 this is where i got messed up i think

okay. so then your equation becomes (1/4)-1-1

or (1/4)-2

right

so evaluate that. that value is your answer.

1/2

how did you get that? post what you did here.

1/4-2/1
2/4
1/2

okay so are you telling me that if you take away 2 dollars from a quarter, you end up with 50 cents?

yeah cause i really hate fractions

-1 3/4

yes, that is right.

ok so then that is the final answer, i will i get them mixed up all the time

okay goodluck.
