Question

5xy^2-7x^3y+2x+1 is a polynomial ?

Answer 1

Answer:

the term 5xy^2-7x^3y+2x+1 is polynomial.

Step-by-step explanation:

We need to determine that the term 5xy^2-7x^3y+2x+1 is a polynomial.

A polynomial is

• combination of terms separated by + or -
• doesn't contain negative powers
• doesn't contain variables in the denominators or under radical expression or trigonometric expressions or logarithm

The term 5xy^2-7x^3y+2x+1 satisfies the definition of polynomial.

So, the term 5xy^2-7x^3y+2x+1 is polynomial.

Answer 2

For this case we have that by definition, a polynomial is an algebraic expression of sums, subtractions and ordered multiplications, composed of variables, constants and exponents.

A polynomial can have more than one variable, constants and exponents, which can only be whole positive numbers.

Thus, the given expression is a polynomial.
