a rectangle has an area of ( x3+x2-10x+8) square meters, and a width of (x+4) meters. Find its length.

    You probably meant to say
    x^3+x^2-10x+8

    since area = l x w
    x^3+x^2-10x+8 = length(x+4)
    length = (x^3+x^2-10x+8)/(x+4)
    = x^2 - 3x + 2

    (I used synthetic division, you could also use long algebraic division)
