1. **State the problem:** Solve the equation $$\sqrt{x}2x + 63 = x$$ for $x$.
2. **Rewrite the equation:** The equation is $$2x\sqrt{x} + 63 = x$$.
3. **Isolate the radical term:** Move $x$ to the left side:
$$2x\sqrt{x} = x - 63$$
4. **Express $\sqrt{x}$ as $x^{1/2}$:**
$$2x \cdot x^{1/2} = x - 63$$
5. **Combine powers of $x$:**
$$2x^{3/2} = x - 63$$
6. **Rewrite as:**
$$2x^{3/2} - x + 63 = 0$$
7. **Substitute $t = \sqrt{x} = x^{1/2}$, so $x = t^2$:**
$$2(t^2)^{3/2} - t^2 + 63 = 0$$
Since $(t^2)^{3/2} = t^{3}$, the equation becomes:
$$2t^3 - t^2 + 63 = 0$$
8. **Solve the cubic equation:**
$$2t^3 - t^2 + 63 = 0$$
9. **Try rational roots:** Possible roots are factors of 63 over factors of 2, e.g., $\pm1, \pm3, \pm7, \pm9, \pm21, \pm63, \pm\frac{1}{2}, \pm\frac{3}{2}, \pm\frac{7}{2}, \pm\frac{9}{2}, \pm\frac{21}{2}, \pm\frac{63}{2}$.
10. **Test $t = -3$:**
$$2(-3)^3 - (-3)^2 + 63 = 2(-27) - 9 + 63 = -54 - 9 + 63 = 0$$
So $t = -3$ is a root.
11. **Factor out $(t + 3)$:**
Divide $2t^3 - t^2 + 63$ by $(t + 3)$:
$$\frac{2t^3 - t^2 + 0t + 63}{t + 3} = 2t^2 - 7t + 21$$
12. **Solve quadratic $2t^2 - 7t + 21 = 0$:**
Discriminant:
$$\Delta = (-7)^2 - 4 \cdot 2 \cdot 21 = 49 - 168 = -119 < 0$$
No real roots.
13. **Real root is $t = -3$ only.**
14. **Recall $t = \sqrt{x} \geq 0$, but $t = -3$ is negative, so discard.**
15. **No real solutions for $x$.**
**Final answer:** No real solution for $x$.
