(a(i))[2]
Factorise $3x^2 + 11x - 4$ into brackets.
(a(ii))[1]
Solve for $x$ in the equation $3x^2 + 11x - 4 = 0$.
(b(i))[4]
Show that $\frac{2}{2x+11} - \frac{1}{x-4} = \frac{1}{2}$ can be reduced to $2x^2 + 3x - 6 = 0$.
(b(ii))[4]
Solve the equation $2x^2 + 3x - 6 = 0$. You must show all working and give your answers correct to 2 decimal places.
