Question

identify the polymomials
1. x power -2 + x power -1 +5
2. 3 x square +7
3. x square + 5under root x
4. 2 under root x​

Answer 1

$\huge \mathcal{QUESTION : }$

Identify the Polynomials :-

1. $\sf {x}^{ (- 2)} + {x}^{( - 1)} + 5$
2. $\tt {3x}^{2} + 7$
3. $\bf {x}^{2} + 5 \sqrt{x}$
4. $\rm 2 \sqrt{x}$

$\huge \mathcal{SOLUTION :}$

• Only the 2nd Option i.e. $\tt {3x}^{2} + 7$ is a polynomial.
