x = 1 only
Explanation:
rewrite as
square both sides
collect like terms and simplify 6
divide by 6 .........
factorise gives x(x - 1) = 0
so possibly x = 0 or x = 1
check in given equation if valid, if x = 0 then 3 = 0 not possible
so x = 0 is not a valid solution.
check in given equation if valid, if x = 1 then 3 = 3 is possible
so x = 1 is a valid solution.
Just to clarify what the previous contributor said.
Explanation:
Isolate the
However, checking in the original equation,
Hopefully this helps!
