1. Solve for $x$: $$2x + 3 = 11$$ 2. Factor the quadratic expression: $$x^2 - 5x + 6$$

1. **Problem:** Find $f^{100}(x)$ for the function $f(x) = 1 - \frac{1}{x}$ defined for all real $x \neq 0, 1$. 2. **Calculate $f^2(x)$:**

1. Problem 1: Solve the quadratic equation $x^2 - 2x = 4$ for $x$. 2. Rewrite the equation in standard form by subtracting 4 from both sides:
