    use the remainder theorem if\[ P(x) = 2x^3 +4x^2 -32x + 18\] and the divisor is (x - 3) the remainder can be found by calculating P(3)

    not quite the remainder \[P(3) = 2(3)^3 + 4(3)^2 - 32(3) + 18\] what's the value...?

    the answer you posted is part of the quotient you don't need to do the division is x - 3 is the divisor the value that makes it equal to zero, that is x = 3 can be substituted into the polynomial to find the remainder

    The remainder is \[\frac{ 12 }{ x-3 }\]

    so you have a common denominator... just add the numerators.... by collecting like terms
