$\sqrt{2 \cdot a} - \sqrt{4 \cdot a}$

Step 1

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

$\sqrt{2 \cdot a} - \sqrt{2^{2} \cdot a}$

Step 2

Pull terms out from under the radical.

$\sqrt{2 \cdot a} - (2 \sqrt{a})$

Step 3

Multiply $2$ by $- 1$ .

$\sqrt{2 \cdot a} - 2 \sqrt{a}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
