1. **State the problem:** Divide the polynomial $$2x^3 - 5x^2 + 3x + 7$$ by the binomial $$x - 2$$.
2. **Formula and method:** Use polynomial long division or synthetic division to divide. Here, we use polynomial long division.
3. **Set up the division:**
$$\frac{2x^3 - 5x^2 + 3x + 7}{x - 2}$$
4. **Divide the leading terms:**
Divide $$2x^3$$ by $$x$$ to get $$2x^2$$.
5. **Multiply and subtract:**
Multiply $$2x^2$$ by $$x - 2$$:
$$2x^2 \times (x - 2) = 2x^3 - 4x^2$$
Subtract this from the original polynomial:
$$\left(2x^3 - 5x^2 + 3x + 7\right) - \left(2x^3 - 4x^2\right) = \cancel{2x^3} - 5x^2 + 3x + 7 - \cancel{2x^3} + 4x^2 = -x^2 + 3x + 7$$
6. **Repeat the process:**
Divide $$-x^2$$ by $$x$$ to get $$-x$$.
7. **Multiply and subtract:**
Multiply $$-x$$ by $$x - 2$$:
$$-x \times (x - 2) = -x^2 + 2x$$
Subtract this from the current remainder:
$$\left(-x^2 + 3x + 7\right) - \left(-x^2 + 2x\right) = \cancel{-x^2} + 3x + 7 - \cancel{-x^2} - 2x = x + 7$$
8. **Continue:**
Divide $$x$$ by $$x$$ to get $$1$$.
9. **Multiply and subtract:**
Multiply $$1$$ by $$x - 2$$:
$$1 \times (x - 2) = x - 2$$
Subtract this from the current remainder:
$$\left(x + 7\right) - \left(x - 2\right) = \cancel{x} + 7 - \cancel{x} + 2 = 9$$
10. **Conclusion:**
The quotient is $$2x^2 - x + 1$$ and the remainder is $$9$$.
11. **Final answer:**
$$\frac{2x^3 - 5x^2 + 3x + 7}{x - 2} = 2x^2 - x + 1 + \frac{9}{x - 2}$$
