The equivalent equation is x² + 20x = -102

<h3>Simplification of quadratic equation</h3>

The equivalent equation can be obtained by factorizing or simplifying the given quadratic equation as shown below;

x² + 20x + 81 = -21

<em>collect similar terms together</em>

x² + 20x + 81 + 21 = 0

x² + 20x + 102 = 0

The equation can also be written as x² + 20x = -102

Thus, the equivalent equation is x² + 20x = -102
