Step 2.1.1

Rewrite $4$ as $2^{2}$ .

$y = \pm \sqrt{2^{2} c x}$

Step 2.1.2

Add parentheses.

$y = \pm \sqrt{2^{2} (c x)}$

Step 2.2

Pull terms out from under the radical.

$y = \pm 2 \sqrt{c x}$

Step 3

The complete solution is the result of both the positive and negative portions of the solution.

Step 3.1

First, use the positive value of the $\pm$ to find the first solution.

$y = 2 \sqrt{c x}$

Step 3.2

Next, use the negative value of the $\pm$ to find the second solution.

$y = - 2 \sqrt{c x}$

Step 3.3

The complete solution is the result of both the positive and negative portions of the solution.

$y = 2 \sqrt{c x}$

$y = - 2 \sqrt{c x}$

$y = 2 \sqrt{c x}$

$y = - 2 \sqrt{c x}$
