simplest form?
3x³ + 2x²-x+ 3
O 3x³ + 2x²-x-3.
O 3x³ + x² - 6x +9
O 3x³ + x² + 6x-9


Sagot :

The polynomial in its simplest form is 3x³ + x² + 6x-9 , Option D is the correct answer.

What are Polynomials ?

The algebraic expression that consists of variables and coefficients are called Polynomials.

It is given that

The variables A, B, and C represent polynomials

where

A = x²

B = 3x + 2

C = x - 3

The Polynomial AB -C² = ?

From the value given

AB -C² = x² (3x + 2) - (x - 3)²

= 3x³  + 2x² - x² - 9 + 6x

= 3x³ + x² + 6x-9

Therefore the polynomial in its simplest form is 3x³ + x² + 6x-9 , Option D is the correct answer.
