Answer by Gogonati(855) (Show Source): You can put this solution on YOUR website!
To solve the equation , we squared both sides of equation
, set the equation equal to zero , using the
quadratic formula we find the roots of the equation.
, and the roots are:
, and .
After checking the roots we reject the root x=-1/2 because it doesn't satisfy the original equation.
Answer: The solution is x=3.
In the same way you can solve the other equations.
