Solve :x² + 1 = 5. Also identify whether x is rational or irrational number. About the author Charlie

Step-by-step explanation: x^2 + 1 = 5 or, x^2 = 5-1 or, x^2 = 4 or, x = √4 = 2 x (2) is a rational number, as it can be written as 2/1 (x/y) Hope it helps 🙂 Reply

Step-by-step explanation:## x = 2

## is correct answer. .

Step-by-step explanation:x^2 + 1 = 5

or, x^2 = 5-1

or, x^2 = 4

or, x = √4 = 2

x (2) is a rational number, as it can be written as 2/1 (x/y)

Hope it helps 🙂
