1. **State the problem:** Simplify or analyze the expression $-4x^{2} + 2x - 3$. 2. **Identify the type of expression:** This is a quadratic polynomial in standard form $ax^{2} + bx + c$ where $a = -4$, $b = 2$, and $c = -3$. 3. **Explain the formula for roots (if needed):** The roots of a quadratic equation $ax^{2} + bx + c = 0$ can be found using the quadratic formula: $$x = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a}$$ 4. **Calculate the discriminant:** $$\Delta = b^{2} - 4ac = 2^{2} - 4(-4)(-3) = 4 - 48 = -44$$ 5. **Interpret the discriminant:** Since $\Delta < 0$, the quadratic has no real roots; it has two complex roots. 6. **Vertex form (optional):** The vertex of the parabola is at $$x = \frac{-b}{2a} = \frac{-2}{2(-4)} = \frac{-2}{-8} = \frac{1}{4}$$ 7. **Evaluate the vertex y-coordinate:** $$y = -4\left(\frac{1}{4}\right)^{2} + 2\left(\frac{1}{4}\right) - 3 = -4\left(\frac{1}{16}\right) + \frac{1}{2} - 3 = -\frac{1}{4} + \frac{1}{2} - 3 = \frac{1}{4} - 3 = -\frac{11}{4}$$ 8. **Summary:** The quadratic $-4x^{2} + 2x - 3$ opens downward (since $a < 0$), has no real roots, and its vertex is at $\left(\frac{1}{4}, -\frac{11}{4}\right)$ which is the maximum point. **Final answer:** The quadratic has no real roots and a vertex at $\left(\frac{1}{4}, -\frac{11}{4}\right)$.
