Question

The degree of the polynomial $f\left(x\right)=(x^2-1)(x-3)$ is

• A. 3.0
• B. 3.00
• C. 03
• D. 3

Answer 1

Answer: (A), (B), (C), (D)

Given: $f\left(x\right)=(x^2-1)(x-3)$
$\Rightarrow f\left(x\right)=x^3-3x^2-x+3$
The degree of a polynomial is the highest of the power of the variable with non-zero coefficients.
$\Rightarrow \text{Degree}f\left(x\right)=3.$
