To calculate: The value of x for the equation
The resultant answer is
Given information:
The equation is
Formula used:
Raise each side of the equation to the same power.
Calculation:
Write the original equation:
Square each side of the equation and simplify,
Isolate the radical,
Divide both sides by 2,
Square once again each side of the equation and simplify,
Factor the equation,
Now check
Now substitute 11 for x and simplify,
Now substitute 4 for x and simplify,
Therefore, the only solution is 4 and the apparent solution 11 is extraneous.
