    the quadratic is positive definite... to check the nature of the solutions use the discriminant \[\Delta = b^2 - 4ac\]

    use this formula.... \[ax ^{2}-bx+c=0\] \[x = \frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }\]

    you may use the formula but you won't get real solutions, you will get complex solutions.
