B. 3x3+6x−2
C. −2x3+4x2+3x−2
D. x3−2x2−4x+1

Respuesta :

Option C is the correct choice   [tex]-2x^4+4x^2+3x-2[/tex],

Remainder of a polynomial by substitution

For a polynomial f(x) to give a remainder of 24 when divided by x + 2:

f(-2) = 24

By testing, substitute x = -2 into the equation [tex]-2x^4+4x^2+3x-2[/tex]

[tex]f(x) = -2x^3+4x^2+3x-2\\\\f(-2)=-2(-2)^3+4(-2)^2+3(-2)-2\\\\f(-2)=-2(-8)+4(4)-6-2\\\\f(-2)=16+16-8\\\\f(-2)=32-8\\\\f(-2)=24[/tex]

Since f(-2) = 24 when x = -2 is substituted into  [tex]-2x^4+4x^2+3x-2[/tex], then  [tex]-2x^4+4x^2+3x-2[/tex] has a remainder of 24 when divided by x+2
