  1. I see no equation

    If you mean y^3 - 1.5y^2 + .3275 = 0
    would rather work with integers, so multiply each term by 400
    400y^3 - 600y^2 + 131 = 0

    I don't know where you are at in your math studies.
    Have you learned a way to solve cubics?
    One way is to use Newton's Method, this requires knowledge of Calculus

    I just ran your equation through Wolfram and got

    Using the original, produced the same results

    Find the polynomials roots to each of the following problems: #1) x^2+3x+1 #2) x^2+4x+3=0 #3) -2x^2+4x-5 #3 is not an equation. Dod you omit "= 0" at the end? #2 can be factored into (x+1)(x+3) = 0, so the roots are x=-1 and -3.

    Show that the equation (1) divided by (x+1) - (x)divided by (x-2)=0 has no real roots Well, to begin, start with 1/(x+1-x). The x's cancel out because they are opposite signs, so now you have 1/1, or just 1. Then, you are dividing
