TABLE OF CONTENTS

Step 1. Given

An equation $x^{2} + 3 x = 4$

To solve the equation

Step 2. Separate the b term

$x^{2} + 3 x = 4 x^{2} + 3 x - 4 = 0 x^{2} + 4 x - x + 4 = 0 (x + 4) (x - 1) = 0$

Step 3. Use Zero-Property

So, either $x + 4 = 0 x = - 4$

Or $x - 1 = 0 x = 1$

The value of $x = - 4, 1$
