A student tries to divide the following polynomial. Based on their work are they correct? If not, where did they go wrong and what is the correct answer?
(2x^3+5x-3)/(x-2)
Wrong, divisor should be 2 and they did not add a 0 for the missing exponent. The correct answer is
2x^2+4x+13+23/(x-2)
(6x^3 +3x^2 -4)-(2x^4+7x^2+8x-4)
-2x^4+6x^3-4x^2-8x
