1. **State the problem:** Solve the quadratic equation $$2x^2 + 3x = 10$$ for $x$, with answers correct to 2 decimal places.
2. **Rewrite the equation:** Move all terms to one side to set the equation to zero:
$$2x^2 + 3x - 10 = 0$$
3. **Identify coefficients:** Here, $a = 2$, $b = 3$, and $c = -10$.
4. **Use the quadratic formula:**
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
5. **Calculate the discriminant:**
$$b^2 - 4ac = 3^2 - 4 \times 2 \times (-10) = 9 + 80 = 89$$
6. **Calculate the roots:**
$$x = \frac{-3 \pm \sqrt{89}}{4}$$
7. **Evaluate the square root and simplify:**
$$\sqrt{89} \approx 9.433$$
8. **Calculate each root:**
$$x_1 = \frac{-3 + 9.433}{4} = \frac{6.433}{4} = 1.61$$
$$x_2 = \frac{-3 - 9.433}{4} = \frac{-12.433}{4} = -3.11$$
9. **Final answer:**
$$x = 1.61 \text{ or } -3.11$$
The larger value is $1.61$ and the smaller is $-3.11$.
