To solve the quadratic equation \(-9x^2 - 2x + 3 = 0\), we can apply the quadratic formula: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] Here, \(a = -9\), \(b = -2\), and \(c = 3\). Plugging in these values: \[ b^2 - 4ac = (-2)^2 - 4(-9)(3) = 4 + 108 = 112 \] Now substituting back into the formula: \[ x = \frac{-(-2) \pm \sqrt{112}}{2(-9)} = \frac{2 \pm \sqrt{112}}{-18} \] Since \(\sqrt{112} = 4\sqrt{7}\), we have: \[ x = \frac{2 \pm 4\sqrt{7}}{-18} \] This simplifies to: \[ x = \frac{-1 \pm 2\sqrt{7}}{9} \] Thus, the two exact solutions are: \[ x = \frac{-1 + 2\sqrt{7}}{9} \] \[ x = \frac{-1 - 2\sqrt{7}}{9} \]
