Question

Write a quadratic polynomial and a cubic polynomial in variable x in the general form.

Answer 1

Answer:

$f(x)=ax^2+bx+c$

$p(x)=ax^3+bx^2+cx+d$    

Step-by-step explanation:

We have to write the general form of a quadratic polynomial and a cubic polynomial in variable x.

Polynomial is an expression which consist of variables and coefficients connected with arithmetic operations.

A Quadratic polynomial of second-degree not larger than the degree 2.

Standard form of quadratic polynomial is

$f(x)=ax^2+bx+c$

where a ≠ 0, and a, b, c are real or complex numbers.

A cubic polynomial is a third-degree polynomial not larger than the degree 3.

Standard form of cubic polynomial is

$p(x)=ax^3+bx^2+cx+d$

where a ≠ 0, and  a,b,c  and d are real or complex numbers.
