    P(1/2) = 2(1/2)^3 - 9(1/2) - 10 P(1/2) = -57/4 P(0) = -10

    2(1/2)^3=1/4 9(1/2)=9/2 1/4-9/2-10 this is where i am stuck what do i do to get the correct answer

    okay so \[\frac{1}{4}-\frac{18}{4}- \frac{40}{4}= -\frac{1-18-40}{4} = \frac{57}{4}\]

    to add and subtract, you have to find a common denominator (preferably a LEAST common denominator) and change the fraction accordingly. Then add and subtract. to multiply, you just multiply numerator by numerator and denominator by denominator to divide, flip (the reciprocal) the fraction right after the dividing sign and then multiply

    lol you're silly. I mean how make fractions come out in equations? like you did there.

    ok thanks. So is equations like latex? That's what I use in latex to do fractions.

    \[4*\frac{1}{4}*\frac{1}{4}*\frac{1}{4} + \frac{9}{4} - 3\] \[\frac{1}{4}*\frac{1}{4} + \frac{9}{4} - 3\] \[\frac{1 * 1}{4 * 4} + \frac{9}{4} - 3\] \[\frac{1}{16} + \frac{9}{4} - 3\] \[\frac{1}{16} + \frac{9 * 4}{4 * 4} - 3\] \[\frac{1}{16} +\frac{36}{16} - 3\] \[\frac{37}{16} - \frac{3}{1}\] \[\frac{37}{16} - \frac{3 * 16}{1 * 16}\] \[\frac{37}{16} - \frac{48}{16}\] \[\frac{-11}{16}\] sorry that took so long...but that was a lot of equations :P

    nope i used my calculator to check, i'm right. you can use matlab, but you don't know how to do fractions? please don't take offense! i'm just curious

    copy this into matlab 4(1/4)^3+9(1/4)-3 ^-- thats the line you gave me it should give you -.6875, which is -11/16

    we might be talking about different things then nvm i'm talking about matlab you're talking about mathlab so nvm :P but i'm sure i'm right, as long as you gave me the right question but since you're trying to understand how to do fraction, just see if you can follow along the steps. because you want to know how to do it, not the answer
