subtract six from both sides to isolate the radical
square each side
add four to each side
subtract x from each side to get a quadratic equation.
factor your equation
solve for each x.
plug in five for x in original problem.
square root of one is one
add one to six
seven does not equal five therefore five is not the answer.
plug in eight to the original equation
the square root of 4 is two.
8=8 there fore the correct answer is eight.
square both sides
subtract one from each side
subtract x from each side
square each side to get rid of the radical
subtract four x from each side
factor out an x from the equation
solve for x
plug four into original equation
find square root of 9 which is three
1 does not equal three so 2 is not an answer
plug zero into original equation
-1 does not equal 1
there is no solution for this equation
