Solve by Factoring square root of 6x^2-x=2x

$\sqrt{6 x^{2} - x} = 2 x$

Step 1

Subtract $2 x$ from both sides of the equation.

$\sqrt{6 x^{2} - x} - 2 x = 0$

Step 2

Factor $x$ out of $6 x^{2} - x$ .

Apply the product rule to $2 x$ .

$6 x^{2} - x = 2^{2} x^{2}$

Raise $2$ to the power of $2$ .

$6 x^{2} - x = 4 x^{2}$

Step 6

Solve for $x$ .

Move all terms containing $x$ to the left side of the equation.

Subtract $4 x^{2}$ from both sides of the equation.

$6 x^{2} - x - 4 x^{2} = 0$

Subtract $4 x^{2}$ from $6 x^{2}$ .

$2 x^{2} - x = 0$

$x = 0$

$2 x - 1 = 0$

Set $x$ equal to $0$ .

$x = 0$

Set $2 x - 1$ equal to $0$ and solve for $x$ .

Set $2 x - 1$ equal to $0$ .

$2 x - 1 = 0$
