Question 925046
{{{P(x)=x^5+x^4-x^3+9}}}



{{{P(c)=c^5+c^4-c^3+9}}}



{{{P(1/2)=(1/2)^5+(1/2)^4-(1/2)^3+9}}} Replace every {{{c}}} with {{{c=1/2}}}



{{{P(1/2)=(1^5)/(2^5)+(1^4)/(2^4)-(1^3)/(2^3)+9}}}



{{{P(1/2)=1/32+1/16-1/8+9}}}



{{{P(1/2)=1/32+2/32-4/32+288/32}}}



{{{P(1/2)=(1+2-4+288)/32}}}



{{{P(1/2)=287/32}}}



-------------------------------------------------------



Answer: 



So, {{{P(1/2)=287/32}}}



{{{P(c)=287/32}}} when {{{c = 1/2}}}
