Problem:

What is the result if x³ - 5x² + x + 15 will be divided by x - 3?

Solution:

Equate first the divisor to zero, then solve for x.

  • x - 3 = 0, then x = 3

Evaluate x³ - 5x² + x + 15, by substituting the value of x which is 3.

  • x³ - 5x² + x + 15
  • (3)³ - 5(3)² + (3) + 15
  • 27 - 5(9) + 3 + 15
  • 27 - 45 + 3 + 15
  • -18 + 18
  • 0

Answer:

∴ Therefore, the result is 0.
