Check whether x^ - 6√x + 2 = 0 is a quadratic equation or not

Open in App

Solution

This is not in quadratic form.Hence it is not a quadratic equation

Even though it is not a quadratic equation, it can be solved by rearrangement to obtain a quadratic equation.

x - 6√x + 2 = 0

x + 2 = 6√x

Squaring both sides

(x + 2)^2 = (6√x)^2
x^2 + 4x +4 = 36x

That is

x^2 -32x +4 = 0

We can solve the above eqn.
