Quadratic Roots Sum Product 828853
1. **State the problem:** Given the quadratic equation $$20x^2 - 23x + 6 = 0$$ with roots $$x_1$$ and $$x_2$$, find the value of $$x_1 \times x_2 + x_1 + x_2$$.
2. **Recall the formulas:** For a quadratic equation $$ax^2 + bx + c = 0$$, the sum and product of roots are:
$$x_1 + x_2 = -\frac{b}{a}$$
$$x_1 \times x_2 = \frac{c}{a}$$
3. **Identify coefficients:** Here, $$a = 20$$, $$b = -23$$, and $$c = 6$$.
4. **Calculate sum of roots:**
$$x_1 + x_2 = -\frac{-23}{20} = \frac{23}{20}$$
5. **Calculate product of roots:**
$$x_1 \times x_2 = \frac{6}{20} = \frac{3}{10}$$
6. **Find the required expression:**
$$x_1 \times x_2 + x_1 + x_2 = \frac{3}{10} + \frac{23}{20} = \frac{6}{20} + \frac{23}{20} = \frac{29}{20}$$
7. **Final answer:**
$$\boxed{\frac{29}{20}}$$
