Easy -1.2 This is a straightforward algebraic fraction simplification requiring factorisation of numerator (x² common factor) and denominator (difference of two squares), then cancellation. It's a single-step problem testing basic factorisation skills with no problem-solving or novel insight required, making it easier than average.
Final answer \(= \frac{x^2}{x+3}\) [Not \(\frac{xx}{x+3}\)]
A1
3 Do not ignore further cancellation
# Question 1:
| Answer/Working | Marks | Guidance |
|---|---|---|
| Attempt to factorise numerator and denominator | M1 | |
| num $= xx(x-3)$ or denom $= (x-3)(x+3)$ | A1 | Not num $= x(x^2-3x)$ |
| Final answer $= \frac{x^2}{x+3}$ [Not $\frac{xx}{x+3}$] | A1 | **3** Do not ignore further cancellation |
