Question

Is √2x-1 a polynomial ? Explain the answer

Answer 1

Answer:

√2x-1=0

√2x=0+1

√2x=1

x=1/2

Answer 2

Answer:

Yes it is polynomial

Step-by-step explanation:

$\sqrt{2}x-1$ is a polynomial (a binomial actually) as it can be expressed in the form of ax+b.

Here a=$\sqrt{2}$ and b=(-1)

[NOTE: if the given question is $\sqrt{2x} - 1$, then it is not a polynomial as $\sqrt{2x} =$$2x^{1/2}$, and the variable of the polynomial cannot have an exponent in fraction.]
