Given the polynomial: f(x)=2x5+mx4−40x3+nx2+218x−168

And that two of the roots are x = 1 and x = 2

You must determine the values of m and n and then use polynomial division to determine the other x-intercepts in order to write the function in factored form. Use polynomials division to determine the other x-intercepts.
