Question

Use factor theorem to verify that x+2 is a factor of x² + 3x²² - 2x - 1₁​

Answer 1

Answer:

Synthetic division is a shortcut for polynomial division when the divisor is a linear factor.

1. Rewrite the dividends coeffiecients in order from largest poOwer to smallest, using a zero if that term doesnt exist.

2. Find the root of the divisor.

3. Keep track of the first coefficient of the dividend, then caclculate the next coeffiecient by multiplying that number by the root found in step 2.

4. Add the number from step 3 with the coeffiecient in the next column to the right.

5. Continue to do this until all coefficients haVe been used If the last number is not 0 that is the remainder.

6. Rewrite answer as a a polynomial
