Remainder Theorem says that if there is any Polynomial equation P(x), which is to be divided by (x - a) then remainder can be calculated by substituting value of a in equation P(x).  

[tex]2x^{4} +x^{2}-10x-1[/tex] = P(x)   divided by   [tex](x+2)[/tex]

Step 1: Find a

To find a we will have to convert (x+2) into (x - a) form

i.e.  (x+2) = (x - (-2))

therefore, a = -2

Step 2: Substitute value of a in P(x),

By substitution we get,

[tex]2(-2)^{4}+(-2)^{2}-10(-2)-1[/tex]

= [tex]2(16) + 4 +20 -1[/tex]

= [tex]32 +4 + 20 - 1[/tex]

= [tex]55[/tex] = Remainder

Hence, Remainder is 55.
