x=22 and x=22

Explanation:

Square both sides:

5x240=0

5x2=40

x2=8

x=±8

x=±22

Both these solutions are valid as they satisfy the original equation.

Hopefully this helps!

x=±8

Explanation:

  1. First, square both sides of the equation, so 5x240=0
  2. Add 40 to both sides: 5x2=40
  3. Divide by 5 on both sides: x2=8
  4. Square root on both sides: x=±8
