Answer:
x = 2 is the solution of the given equation
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given equation
squaring on both sides , we get
⇒ x + 2 = x²
⇒x² - x -2 =0
<u><em>Step(ii)</em></u>:-
Given x² - x -2 =0
⇒ x² - 2x + x - 2 =0
⇒ x ( x-2) + 1(x - 2) =0
⇒ (x + 1) ( x-2) =0
⇒ x = -1 and x =2
x = 2 is the solution of the given equation
<u><em>Verification</em></u>:-
Put x= 2
2 = 2
