Question

(5x^3-6-15x) / (10+5x)? I need help please...

Answer 1

Answer:

  (x^2 -2x +1) -16/(5x+10)

Step-by-step explanation:

The quotient and remainder can be found by polynomial long division or by synthetic division.

___

For synthetic division, it is recommended to divide the dividend and divisor by the leading coefficient of the divisor (5), so the divisor coefficient is 1. This results in a divisor of (x+2) and a remainder of -16/5. The simplified remainder becomes ...

  (-16/5)/(x+2) = -16/(5x +10)

See the attachments for the various methods of computing the quotient.
