Based on the calculations, the unknown polynomial is equal to 5x.

What is a polynomial?

A polynomial can be defined as a mathematical expression which comprises intermediates (variables), constants, and whole number exponents with different numerical value, that are typically combined by using mathematical operations such as:

  • Addition
  • Subtraction
  • Multiplication

Since the product (multiplication) of 2x² - 3x + 4 and another polynomial is equal to 10x³ - 15x² + 20, let the unknown polynomial be denoted by P(x). Thus, this is given by this expression:

P(x) × (2x² - 3x + 4) =  10x³ - 15x² + 20

P(x) = (10x³ - 15x² + 20)/(2x² - 3x + 4)

Dividing the two polynomials, we have:

10x³ - 15x² + 20  |2x² - 3x + 4

-                           5x

(10x³ - 15x² + 20)
