Answer:
see explanation
Step-by-step explanation:
One way to divide is to use the divisor as a factor in the numerator
Consider the numerator
x²(x - 3) + 3x² - x + 6
= x²(x - 3) + 3x(x - 3) + 9x - x + 6
= x²(x - 3) + 3x(x - 3) + 8(x - 3) + 24 + 6
= x²(x - 3) + 3x(x - 3) + 8(x - 3) + 30
quotient = x² + 3x + 8 , remainder = 30
= x² + 3x + 8 + ![\frac{30}{x-3}](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7Bx-3%7D)
