This is a problem in either long division
or synthetic division, depending on which
you are studying.
Write 3x³ - 5 as 3x³ + 0x² + 0x - 5
By long division:
3x² + 3x + 3
x - 1)3x³ + 0x² + 0x - 5
3x³ - 3x²
3x² + 0x
3x² - 3x
3x - 5
3x - 3
So using the formula:
Do you understand the steps in long division?
If not post again, asking to list the steps.
By synthetic division:
1 | 3 0 0 -5
| 3 3 3
3 3 3 -2
Which is interpreted as
Do you understand the steps in synthetic
division, if that is what you are
studying? If not post again asking
to go through the steps.
