Question

what must be added to x^5-9x-12 so that the resulting polynomial is exactly divisible by x^2+3.can u say the answer ​

Answer 1

Answer:

Therefore, −(−x+2) that is x−2 must be added to the given polynomial so that the resulting polynomial is exactly divisible by x2+2x−3. Hence, (x−2) must be added to the polynomial x4+2x3−2x2+x−1 so that the resulting polynomial is exactly divisible by x2+2x−3.
