Question

Classify the following polynomial as linear, quadratic, cubic and biquadratic polynomial:

$t^2+9$

Answer 1

Classifying the given polynomial:

Degree of Polynomial: If a polynomial is in one variable, the highest power of the polynomial is called the degree of the polynomial.

Quadratic Polynomial: A polynomial of degree two is called quadratic polynomial.

Since $t^2+9$ is a polynomial in one variable $\left(t\right)$, and of degree $2$, it is a quadratic polynomial.

Therefore, $t^2+9$ is a quadratic polynomial.
