Chapter 8.4, Problem 3MCQ

To determine

The polynomial $4x+3x^2$ in standard form and name polynomial based on degree and number of terms.

Answer to Problem 3MCQ

The standard form of polynomial is $3x^2+4x$ .

The is Quadratic polynomial.

And according to number of terms polynomial is Binomial.

Explanation of Solution

Given information:

The polynomial $4x+3x^2$

Concept and Formula Used:

The standard form of a polynomial is a form in which terms are written in decreasing order of degree of variable i.e. $a_1{x}^n+a_2{x}^{n-1}+a_3{x}^{n-2}+\mathrm{..................}+a_n{x}^0$

Degree is the highest power of variable in a polynomial.

Based on degree polynomial are classified into : 1 degree Linear, 2 degree Quadratic and 3 degree Cubic

Based on number of terms polynomial are classified as Monimal containing one term, Binomial with two terms and Trinomial polynomial with three terms.

Calculation:

The givenpolynomial is $4x+3x^2$

The standard form of polynomial is $a_1{x}^n+a_2{x}^{n-1}+a_3{x}^{n-2}+\mathrm{..................}+a_n{x}^0$

The standard form of polynomial

  $4x+3x^2=3x^2+4x$

The degree of polynomial is 2 therefore it is Quadratic polynomial.

Number of terms are 2 therefore polynomial is binomial.

Conclusion:

The standard form of polynomial is $3x^2+4x$ .

The is Quadratic polynomial.

And according to number of terms polynomial is Binomial.
