Question 93232
{{{f(x)=-x^2-3x+5}}} Start with the given polynomial



{{{f(-6)=-(-6)^2-3(-6)+5}}} Plug in {{{x=-6}}}



{{{f(-6)=-36-3(-6)+5}}} Evaluate {{{(-6)^2}}} to get 36

 

{{{f(-6)=-36-3(-6)+5}}} Multiply -1 and  36  to get -36

   

{{{f(-6)=-36+18+5}}} Multiply -3 and  -6  to get 18

  

{{{f(-6)=-13}}} Now combine like terms
