Quadratic Solve 65E3C7
1. The problem is to solve the quadratic equation $2x^2 - 5x + 3 = 0$.
2. We use the quadratic formula to solve equations of the form $ax^2 + bx + c = 0$:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a=2$, $b=-5$, and $c=3$.
3. Calculate the discriminant:
$$\Delta = b^2 - 4ac = (-5)^2 - 4 \times 2 \times 3 = 25 - 24 = 1$$
4. Since $\Delta > 0$, there are two distinct real roots.
5. Substitute values into the quadratic formula:
$$x = \frac{-(-5) \pm \sqrt{1}}{2 \times 2} = \frac{5 \pm 1}{4}$$
6. Calculate each root:
- For $+$ sign: $x = \frac{5 + 1}{4} = \frac{6}{4} = 1.5$
- For $-$ sign: $x = \frac{5 - 1}{4} = \frac{4}{4} = 1$
7. Therefore, the solutions are $x = 1.5$ and $x = 1$.
