Let's solve your equation step-by-step.
x² + 4x = 5
Step 1: Subtract 5 from both sides.
x² + 4x - 5 = 5 - 5
x² + 4x - 5 = 0
Step 2: Factor left side of equation.
(x-1) (x+5) = 0
Step 3: Set factors equal to 0.
x-1 = 0 or x + 5 = 0
x = 1 or x = - 5

x² + 4x = 5
x² + 4x - 5 = 5 - 5
x² + 4x - 5 = 0
x² + 5x - x - 5 = 0
x (x) + x (5) - 1 (x) - 1 (5) = 0
(x - 1) (x + 5) = 0
x - 1 = 0 or x + 5 = 0
+ 1 + 1 - 5 - 5
x = 1 x = - 5
