Question 198724
{{{P(x)=2x^4+x^3+12}}} Start with the given equation.



{{{P(-1/2)=2(-1/2)^4+(-1/2)^3+12}}} Plug in {{{x=-1/2}}}.



{{{P(-1/2)=2(1/16)+(-1/2)^3+12}}} Raise  {{{-1/2}}} to the 4th power to get {{{1/16}}}.



{{{P(-1/2)=2(1/16)-1/8+12}}} Cube {{{-1/2}}} to get {{{-1/8}}}.



{{{P(-1/2)=1/8-1/8+12}}} Multiply {{{2}}} and {{{1/16}}} to get {{{1/8}}}.



{{{P(-1/2)=12}}} Combine like terms.
