Answer 1

Answer:

What should be subtracted from the polynomial x4+2x3+x2-18x-15 so that the resulting polynomial is exactly divisible by x2-1-x.Hint: Subtract the remainder

Answer 2

Answer:

divide x^4+2x^3+x2-18x-15 by x^2-x-1, you will get x^2+3x+5 as quotient and -10x-10 as remainder

Subtract -10x-10 from the polynomial
