Answer 1

Answer:

Electrolysis of water is the process of using electricity to decompose water into oxygen and hydrogen gas. Hydrogen gas released in this way can be used as hydrogen fuel, or remixed with the oxygen to create oxyhydrogen gas, which is used in welding and other applications.

Explanation:

x = (2 + √5)

x = (2 + √5)x + 1/x

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)(2 + √5)² + 1/(2 + √5)

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)(2 + √5)² + 1/(2 + √5)= 4 + 5 + 4√5 + 1 / (2 +√5)

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)(2 + √5)² + 1/(2 + √5)= 4 + 5 + 4√5 + 1 / (2 +√5)= 10 + 4√5 / ( 2 + √5)

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)(2 + √5)² + 1/(2 + √5)= 4 + 5 + 4√5 + 1 / (2 +√5)= 10 + 4√5 / ( 2 + √5)= 10 + 4√5(2 - 4√5) / 2² - √5²

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)(2 + √5)² + 1/(2 + √5)= 4 + 5 + 4√5 + 1 / (2 +√5)= 10 + 4√5 / ( 2 + √5)= 10 + 4√5(2 - 4√5) / 2² - √5²= 20 -40√5 +8√5 - 90 / 4 - 5

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)(2 + √5)² + 1/(2 + √5)= 4 + 5 + 4√5 + 1 / (2 +√5)= 10 + 4√5 / ( 2 + √5)= 10 + 4√5(2 - 4√5) / 2² - √5²= 20 -40√5 +8√5 - 90 / 4 - 5= -70 - 32√5 / -1

x = (2 + √5)x + 1/x= 2 + √5 + 1/(2 + √5)(2 + √5)² + 1/(2 + √5)= 4 + 5 + 4√5 + 1 / (2 +√5)= 10 + 4√5 / ( 2 + √5)= 10 + 4√5(2 - 4√5) / 2² - √5²= 20 -40√5 +8√5 - 90 / 4 - 5= -70 - 32√5 / -1= 70 + 32√5
