    There are two solutions to <u>every</u> quadratic equation.
If you cannot easily see how to factor the expression, then you can always use the quadratic formula. In this case,
x = (-6±√(36+84))/-14 = (3±√30)/7

    to find the nature of the roots (solutions)
you can solve it with the quadratic formula (or factoring)
or ... find the discriminant ... b^2 - 4 a c

    There are 2 solutions because a graph of the function crosses the x-axis
twice.
    
twice.
