Question

9x*-3x=3(12-2x)​

Answer 1

$9 {x}^{2} - 3x = 3(12 - 2x) \\ 9 {x}^{2} - 3x = 36 - 6x \\ 9 {x}^{2} + 3x - 36 = 0 \\ 3 {x}^{2} + x - 12 = 0 \\ d = {1}^{2} - 4 \times 3 \times ( - 12) = 145 \\ x_{1} = \frac{ - 1 + \sqrt{145} }{6} \\ x_{2} = \frac{ - 1 - \sqrt{145} }{6}$

Answer 2

To solve the equation 9x*-3x = 3(12-2x), we need to simplify the equation and then solve for the variable x.

First, let's simplify the equation step by step:

9x*-3x = 3(12-2x)

Simplifying the left side of the equation: 9x*-3x can be written as -27x^2.

So now our equation becomes: -27x^2 = 3(12-2x)

Next, let's distribute 3 to the terms inside the parentheses: -27x^2 = 36 - 6x

Now, we have a quadratic equation. Let's rearrange it to set it equal to zero: -27x^2 + 6x - 36 = 0

To simplify further, we can divide the entire equation by -3: 9x^2 - 2x + 12 = 0

Now, we can solve this quadratic equation. However, it appears that the equation you provided contains a typographical error. The term "9x*" doesn't have a clear meaning. Please double-check the equation and provide the correct expression, so we can assist you further.
