How do I solve this equation and check the solutions?

{12}

Step-by-step explanation:

isolate the radical expression

raise both sides to the index of the radical in this case 2

foil the right hand side or multiply (x-6)(x-6)

subtract 3x from both sides and combine like terms

factor

set each factor equal to zero and solve for x

x - 12 = 0 and x - 3 = 0

     x = 12 and     x  = 3

Check each answer by plugging them individually into the original equation if the come out true they are a solution.

Check :

So the only solution is 12.

1; 35 is the ratio
