Short Answer

Expert verified

The solution for the equation is $d = 121$ .

Step by step solution

Step 1. Write down the given equation.

The given equation is $d + \sqrt{d} - 132 = 0$ .

Step 2. Simplify the equation.

The given equation $d + \sqrt{d} - 132 = 0$ is solved as:

$\begin{matrix} d + \sqrt{d} - 132 = 0 .... (Given) \\ (\sqrt{d} - 11) (\sqrt{d} + 12) = 0 \\ \sqrt{d} - 11 = 0 or \sqrt{d} + 12 = 0 \\ \sqrt{d} = 11 or \sqrt{d} = - 12 \\ d = 121 or \sqrt{d} = - 12 .... (Impossible) \\ d = 121 \end{matrix}$

Step 3. Conclusion.

The solution for the given equation is $d = 121$ .
