In this video, the steps and rules used to solve question 4 in grade 9 practice on simplifying rational expressions are presented.
Question: Simplify the rational expressions
a) \( \quad \displaystyle \frac{-3x+2}{x-1} \cdot \frac{2x-2}{3x - 2} \) b) \( \quad \displaystyle \frac{(2n+3)(3n+15)}{(n-5)(6n + 9)} \)
c) \( \quad \displaystyle \frac{2x^2 + x}{ x(2x + 1)} \) d) \( \quad \displaystyle \frac{x^2 + 2x - 3}{ (x+3)(2x-2)} \)
