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

Naily [24]

Answer:

Step-by-step explanation:

.25x + .125x + 24 = 60

.25x + .125x = .375x

.375x + 24 = 60

60 - 24 = 36

.375x = 36

36/ .375

x = 96
