The root of x = -2 + √2
Step-by-step explanation:
<u><em> Step(i):-</em></u>
Given

⇒
<u><em>Step(ii):-</em></u>
Rationalizing
Apply ( a-b ) ( a+b) = a²-b²
The root of x = -2 + √2
For this case we can algebraically rewrite the expression given as:
Where:
x: Represents the unknown number
Subtracting 8 from both sides of the inequality we have:
Dividing between 4 on both sides of the inequality:
We multiply by -1 on both sides taking into account that the sense of inequality changes:
