In this video, the steps and rules used to solve question 6 in grade 9 practice on factoring algebraic expressions using three techniques are presented.
Question: Factor the expressions
a) \( \quad 4x - 16 \) b) \( \quad 6 x^2 + 2 x \)
c) \( \quad x^2 - 9 \)
d) \( \quad 9x^2 - 16 y^2 \) e) \( \quad x^2 - 4x - 5 \) f) \( \displaystyle \quad \frac{1}{2} x^2 + x + \frac{1}{2} \)
