Answer:
Yes, it is a quadratic equation.
Step-by-step explanation:
<em>Let's solve it to make it a quadratic equation:</em>
=> 
=> x²+1 = 5x²
=> 5x²-x²-1 = 0
=> 4x²-1 = 0
<em>Comparing it with the standard form of quadratic equation i.e. </em>

So, we get
a = 4 , b = 0 and c = -1
<u><em>So, yes. It is a quadratic equation and it is a pure quadratic equation since b is equal to 0.</em></u>
