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?
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?
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
so evaluate that. that value is your answer.
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?
http://www.youtube.com/watch?v=52ZlXsFJULI go through that video. It will teach you how to how to add and subtract fractions.
yeah cause i really hate fractions
yes, that is right.
go through some videos on how to add and subtract the fractions. The video I posted helps you think about fractions intuitively.
ok so then that is the final answer, i will i get them mixed up all the time
