- Question 6(a): $\begin{pmatrix} -p \\ -p-1 \end{pmatrix}$
- Question 6(b): $\begin{pmatrix} 3x \\ 3y \end{pmatrix}$
- Question 6(c): $\begin{pmatrix} 2m \\ m \end{pmatrix}$
- Question 6(d): $\begin{pmatrix} -2a & 0 \\ 0 & 2a \end{pmatrix}$
- Question 6(e): $\begin{pmatrix} 12t & 0 \\ 0 & 12t \end{pmatrix}$
- Question 6(f): $\begin{pmatrix} -3 \\ 2 \end{pmatrix}$
- Question 7(a): $\begin{pmatrix} 2x^2 + 9 & 6x^2 \\ -5x - 12x & -15x \end{pmatrix}$
- Question 7(b): $\begin{pmatrix} 7a - 30a & 8a + 33a \\ -14 - 10 & -16 + 11 \end{pmatrix} = \begin{pmatrix} -23a & 41a \\ -24 & -5 \end{pmatrix}$
- Question 7(c): $\begin{pmatrix} x^2 & 0 \\ 2x & x^2 \end{pmatrix}$
- Question 7(d): $\begin{pmatrix} 2y & 3y^2 + y \\ -6 & -9y + x \end{pmatrix}$
- Question 7(e): $\begin{pmatrix} (a+1)^2 - a(a+2) & -(a+1)a + a(a+1) \\ (a+2)(a+1) - (a+1)(a+2) & -(a+2)a + (a+1)^2 \end{pmatrix} = \begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}$
- Question 7(f): $\begin{pmatrix} 9x^2 + 27 & -9x - 3(x+1) \\ -27x - 9(x+1) & 81 + (x+1)^2 \end{pmatrix} = \begin{pmatrix} 9x^2 + 27 & -12x - 3 \\ -36x - 9 & x^2 + 2x + 82 \end{pmatrix}$
