Question

which of following expression are
Polynomials in one variable and which
are not state reasons for your answer 4x2-3x+7

​

Answer 1

Answer:

All the exponents of x are whole numbers. ∴ 4x2 – 3x + 7 is a polynomial in one variable.

Answer 2

Explanation:

Given:

4x²- 3x + 7

Reason:

The given expression is in one variable x and all the powers of a variable are integers.

The exponent of x is the whole number i.e, 2. Hence, the given expression 4x² - 3x + 7 is a polynomial in one variable.

4x² - 3x + 7 is a polynomial in one variable.
