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