# Determine the solution set of x^{2} - 80 = 0.

**Solution:**

The given equation is

x^{2} - 80 = 0

x^{2} = 80

x^{2} = 16 × 5

x = ± √16 × 5

x = ± 4(√5)

Another similar example can be to determine the solution set of x^{2} - 128 = 0

x^{2} - 128 = 0

x^{2} =128

x^{2} = 64 × 2

x = ± √64 × 5

x = ± 8(√2)

## Determine the solution set of x^{2} - 80 = 0.

**Summary:**

The solution set of x^{2} - 80 = 0 is x = ± 4(√5)
