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
Answer:
Imaginary numbers.
Step-by-step explanation:
Not sure quite what the question is asking, but negative square roots will give an answer in terms of 'i' - which is an imaginary number.

Answer:
y(x)=2x^3-6x^2+ax+b, a and b are constants
Step-by-step explanation:
d2y/dx2=12x-12, integrating both sides we get
dy/dx=6x^2-12x+a, where a is the integration constant.
Again integrating both sides, we get
y(x)=2x^3-6x^2+ax+b, where b is the integration constant
