Answer :

To solve the equation [tex]\(\sqrt{3 - 3x} = 3 + \sqrt{3x + 2}\)[/tex], we will follow these algebraic steps:

1. Isolate one of the square roots:

[tex]\[ \sqrt{3 - 3x} = 3 + \sqrt{3x + 2} \][/tex]

To isolate the square root on the left, we leave it as it is for now.

2. Square both sides to eliminate the square root:

[tex]\[ (\sqrt{3 - 3x})^2 = (3 + \sqrt{3x + 2})^2 \][/tex]

Simplifying both sides, we get:

[tex]\[ 3 - 3x = 9 + 6\sqrt{3x + 2} + (3x + 2) \][/tex]

3. Combine like terms:

[tex]\[ 3 - 3x = 9 + 6\sqrt{3x + 2} + 3x + 2 \][/tex]

Simplifying the right side further:

[tex]\[ 3 - 3x = 11 + 6\sqrt{3x + 2} + 3x \][/tex]

4. Isolate the term involving the square root:

[tex]\[ 3 - 3x - 11 - 3x = 6\sqrt{3x + 2} \][/tex]

Combine the constants and linear terms on the left:

[tex]\[ -8 - 6x = 6\sqrt{3x + 2} \][/tex]

5. Divide both sides by 6 to simplify:

[tex]\[ \frac{-8 - 6x}{6} = \sqrt{3x + 2} \][/tex]

Simplifying the left side:

[tex]\[ -\frac{4 + 3x}{3} = \sqrt{3x + 2} \][/tex]

6. Square both sides again to eliminate the remaining square root:

[tex]\[ \left(-\frac{4 + 3x}{3}\right)^2 = (3x + 2) \][/tex]

Simplify each side:

[tex]\[ \left(\frac{4 + 3x}{3}\right)^2 = 3x + 2 \][/tex]

Expanding the square on the left:

[tex]\[ \frac{(4 + 3x)^2}{9} = 3x + 2 \][/tex]

7. Clear the fraction by multiplying each term by 9:

[tex]\[ (4 + 3x)^2 = 9(3x + 2) \][/tex]

Expanding both sides:

[tex]\[ 16 + 24x + 9x^2 = 27x + 18 \][/tex]

8. Combine like terms and set the equation to zero:

[tex]\[ 9x^2 + 24x + 16 = 27x + 18 \][/tex]

Bring all the terms to one side:

[tex]\[ 9x^2 + 24x + 16 - 27x - 18 = 0 \][/tex]

Simplifying:

[tex]\[ 9x^2 - 3x - 2 = 0 \][/tex]

9. Use the quadratic formula [tex]\(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\)[/tex] to solve for [tex]\(x\)[/tex]:

Here, [tex]\(a = 9\)[/tex], [tex]\(b = -3\)[/tex], and [tex]\(c = -2\)[/tex].

[tex]\[ x = \frac{-(-3) \pm \sqrt{(-3)^2 - 4(9)(-2)}}{2(9)} \][/tex]

Simplifying inside the square root:

[tex]\[ x = \frac{3 \pm \sqrt{9 + 72}}{18} \][/tex]

[tex]\[ x = \frac{3 \pm \sqrt{81}}{18} \][/tex]

[tex]\[ x = \frac{3 \pm 9}{18} \][/tex]

Solving for the two cases:

[tex]\[ x = \frac{3 + 9}{18} = \frac{12}{18} = \frac{2}{3} \][/tex]

[tex]\[ x = \frac{3 - 9}{18} = \frac{-6}{18} = -\frac{1}{3} \][/tex]

10. Check both potential solutions in the original equation:

[tex]\[ \sqrt{3 - 3 \left( \frac{2}{3} \right)} = 3 + \sqrt{3 \left( \frac{2}{3} \right) + 2} \][/tex]

[tex]\[ \sqrt{3 - 2} = 3 + \sqrt{2 + 2} \][/tex]

[tex]\[ \sqrt{1} = 3 + \sqrt{4} \][/tex]

[tex]\[ 1 = 3 + 2 \][/tex]

This is not true, so [tex]\(x = \frac{2}{3}\)[/tex] is not a solution.

Similarly, for [tex]\(x = -\frac{1}{3}\)[/tex]:

[tex]\[ \sqrt{3 - 3 \left( -\frac{1}{3} \right)} = 3 + \sqrt{3 \left( -\frac{1}{3} \right) + 2} \][/tex]

[tex]\[ \sqrt{3 + 1} = 3 + \sqrt{-1 + 2} \][/tex]

[tex]\[ \sqrt{4} = 3 + \sqrt{1} \][/tex]

[tex]\[ 2 = 3 + 1 \][/tex]

This is also not true, so [tex]\(x = -\frac{1}{3}\)[/tex] is not a solution either.

Therefore, after thoroughly checking both potential solutions, we find that there are no valid solutions to the given equation. Thus, the solution set is empty.

[tex]\[ \boxed{\emptyset} \][/tex]
