e) \((x - 3)^2 = (2x - 1)^2\)
f) \(3x^2 - 11x + 6 = 0\)
g) \(\frac{x + 6}{x + 5} + \frac{3}{2} = 2\)
h) \(\frac{2}{x - 2} + \frac{3}{3 - x} = \frac{3x - 20}{(x - 3)(x - 2)}\)
i) \(\frac{1}{x - 1} - \frac{4x}{x - 3} = \frac{x}{x^2 + x + 1}\)
j) \(\frac{x - 1}{x + 3} - \frac{x}{x - 3} = \frac{7x - 3}{9 - x^2}\)
