Solve the radical equation
Hint:
Rearrange the equation and then solve for x.
The correct answer is: x = 6/49
Complete step by step solution:
Here we have the equation
On squaring both the sides, we have
On subtracting, 6x and 9 from both the sides, we get
On squaring both the sides, we get
Now, this is a quadratic equation with a = 49, b = -300, c = 36
Roots can be found with,
On solving, we get
Here, on substituting in given equation we get
Hence x = 6 works.
Now,
Here does not work.
Hence is an extraneous solution.
