    \[x ^{2} + 14x = -130\]

    it's good to know alternate and quick methods sometimes. Substitute each pair values to see if they = -130

    add 130 to both sides. Now use discriminant b^2 - 4ac, for ax^2 +bx + c. Remember that when this is less than 0, there are no real solutions. This is the case for this quadratic, since 14^2< 4*130
