You can put this solution on YOUR website!
x%5E2-9x-4=6

x%5E2-9x-4-6=6-6 Subtract 6 from both sides

x%5E2-9x-10=0 Combine like terms

Now lets factor

ERROR Algebra::Solver::Engine::invoke_solver_noengine: solver not defined for name 'quadratic_factoring'.
Error occurred executing solver 'quadratic_factoring' .



So x%5E2-9x-10=0 factors to

%28x%2B1%29%28x-10%29=0
Now set each factor equal to zero
Let x+1 equal zero
x%2B1=0
x=-1
Now let x-10 equal zero
x-10=0
x=10
So our solution is
x=-1 or x=10
