The solution of x in -6 + 3x - 9x^2 = -16 is x = \frac{3 \pm \sqrt{369}}{18}

<h3>How to solve the equation?</h3>

The equation is given as:

-6 + 3x - 9x^2 = -16

Add 16 to both sides

10 + 3x - 9x^2 = 0

Rewrite as:

9x^2 - 3x - 10 = 0

Solve for x using the quadratic formula

x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

So, we have:

x = \frac{3 \pm \sqrt{(-3)^2 - 4 * 9 * -10}}{2 * 9}

Evaluate

x = \frac{3 \pm \sqrt{369}}{18}

Hence, the solution of x in -6 + 3x - 9x^2 = -16 is x = \frac{3 \pm \sqrt{369}}{18}
