Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website! First get all terms to one side by subtracting 3 from both sides
Now lets factor out a negative 1
Now lets factor the quadratic in the parenthesis:
ERROR Algebra::Solver::Engine::invoke_solver_noengine: solver not defined for name 'quadratic_factoring'.
-------------------------------------------------------------------------
So in other words, the quadratic factors to Divide both sides by -1
Set each term equal to zero
So our solutions are: and which are both real
We can verify this with a graph graph of
