Need some help with using synthetic division to find the function value of this problem:

f(x)=2x^4+4x^3+2x^2+3x+8;find f(-2)

  • Algebra -

    hard to line up the spacing with this font format, but here it goes

    -2│2 4 2 3 8
    ***----------
    *** -4 0-4 2
    ** 2 0 0-1 10

    so f(-2) = 10

  • correction -

    the last row in the synthetic division algorithm should have been

    ** 2 0 2 -1 10
