Question

Classify the following as linear, quadratic, cubic and constant polynomials:

(iii) $79$

Answer 1

• Degree: The degree of a polynomial is the highest value of the power of the variable in the polynomial. For example: the degree of the polynomial $x^2+1$ is $2$ as the value of the highest power of the variable in the polynomial is $2$.
• Linear polynomial are the polynomials of degree one. For example: $x+1$
• Quadratic polynomials are the polynomials of degree two. For example:$x^2+3x$
• Cubic polynomials are the polynomials of degree three. For example: $x^3+2x+1$
• Constant polynomials are the polynomials of degree zero or the polynomials which do not have any variable in it.
• It can be observed that the given polynomial, i.e., $79$ do not have any variable. Thus, the given polynomial is a constant polynomial.
• Final Answer: The polynomial $79$ is a constant polynomial.
