The first part of the question is okay.
The second part which is to write the answer in qoutient, remainder and divisor form:
-2x³ + 5x² - x + 3
x - 3
Divide -2x³ + 5x² - x + 3 : -2x³ + 5x² - x + 3
x - 3 x - 3
= - 2x² + -x² - x + 3
x - 3
Divide -x² - x + 3 : -x² - x + 3
x - 3 x - 3
= -x + -4x + 3
x - 3
= -2x² - x + -4x + 3
x - 3
Divide -4x + 3 : -4x + 3
x - 3 x - 3
= -4 + -9
x - 3
= -2x² - x - 4 + -9
x - 3
Therefore, the quotient, remainder and divisor form is:
= -2x² - x - 4 - 9
x - 3
