Answer:
- x² + x + 1 and remainder 2
Step-by-step explanation:
<u>Given</u>
Without using a synthetic division, we can use easier method to find the quotient.
<u>We know the formula:</u>
- x³ - 1 = (x - 1)(x² + x + 1)
<u>Rewrite the given as:</u>
- x³ + 1 =
- x³ - 1 + 2 =
- (x - 1)(x² + x + 1) + 2
This expression, when divided by (x - 1) leave the quotient (x² + x + 1) and a remainder of 2
