Short Answer

Expert verified

$a = 6.96$

Step by step solution

Step 1. Given Information.

The given equation is $2 a^{2} + 1 = 98$ .

Step 2. Calculation.

The solution of the given equation will be

$\begin{matrix} 2 a^{2} + 1 = 98 \\ 2 a^{2} = 98 - 1 \\ 2 a^{2} = 97 \\ a = \sqrt{\frac{97}{2}} \end{matrix}$

Simplify it further.

$\begin{matrix} a = 6.9641 \\ a \approx 6.96 \end{matrix}$

Step 3. Conclusion.

The solution of the given equation is $a = 6.96$ .
