Question

Which of the following expression are polynomial in one variable and which not state reason for your answer (1) 4x2 -3x+7 (2) y2 + square root 2

Answer 1

Answer:

Both are Polynomial in one variable.

Step-by-step explanation:

Polynomials are Algebraic expressions that do not contain any fractional in or negative power of variables....So in this Problem both contain power as positive intergers only and variable is single.

Answer 2

Step-by-step 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.
