Question

If the polynomial x5 − 105 can be split as the product of the polynomials
x − 10 and a, what is a?



x4 − 99,990



x4 + 10x3 + 100x2 + 1,000x − 10,000



x4 + 10x3 + 100x2 + 1,000x + 10,000

Answer 1

d) x4-99,990/x-10

Answer 2

Do you know how to use long division or synthetic division

Answer 3

Use synthetic division to find the quotient.
Don't forget to use zero as a placeholder for missing terms:
x^5 − 105 = x^5 + 0x^4 + 0x^3 + 0x^2 + 0x - 105
