Solution to 1/4x^2-4=0??

x = 4 or x = -4

Step-by-step explanation:

Solve for x over the real numbers:

x^2/4 - 4 = 0

The left hand side factors into a product with three terms:

1/4 (x - 4) (x + 4) = 0

Multiply both sides by 4:

(x - 4) (x + 4) = 0

Split into two equations:

x - 4 = 0 or x + 4 = 0

Add 4 to both sides:

x = 4 or x + 4 = 0

Subtract 4 from both sides:

| x = 4 or x = -4
