EQUATIONS CONTAINING VARIABLES UNDER ONE OR MORE RADICALS
Isolate the radical term
Raise both sides of the equation to the power 3 and simplify.bf
The answer is x=-206
Check the solution by substituting -206 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.bf
Right Side: 0
Since the left side of the original equation equals the right side of the original equation after you substitute -206 for x, then -206 is a solution.
You can also check your solution by graphing the function
The above function is formed by subtracting the right side of the original equation from the left side of the original equation. The x-intercept of the graph is the solution to the original equation. As you can see, there is one x-intercept at -206. We have verified our solutions graphically.
