Question:
Let $'a'$ be the real root of the equation $x^3 - 3x^2 + 5x - 17 = 0$ and $'b'$ be the real root of the equation $x^3 - 3x^2 + 5x + 11 = 0$. Then $a + b = $ ____.
Step-by-Step Solution
Key Concept: Cubic functions possess point symmetry about their inflection point, which simplifies analysis of their properties.
The concept of inflection point of a cubic function states that a cubic graph is symmetrical about its inflection point. This symmetry property is used to analyze the behavior and key characteristics of cubic functions.
