Question

x^-2+2x^-1+3 find its a polynomial or not if yes write it's degree​

Answer 1

Answer:

No, it's not a polynomial.

Step-by-step explanation:

No, it's not a polynomial as the degree is -2 and when the degree is -2, it is not a polynomial. The degree Should be in positive, then only it will be a polynomial.

Answer 2

Answer:

Given⤵

$➡{x}^{ - 2} + {2x}^{ - 1} + 3$

To find⤵

➡It's a polynomial or not if yes then write it's degree.

Solution⤵

⚫No, It is not a polynomial.

⚫In polynomial the exponent of variable must be non negative integer. But here the exponent of variable (x) is -2.

$✅Hence , {x}^{ - 2} + {2x}^{ - 1} + 3 \: is \: not \: a \: polynomial$

✔Extra points⤵

✡Polynomial:-

Polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
