(a(i))[2]
Factorise the quadratic $24 + 5x - x^2$.
(a(ii))[3]
Find the values of $a$, $b$ and $c$.
(a(iii))[3]
Calculate the gradient for $y = 24 + 5x - x^2$ when $x = -1.5$.
(b(i))[4]
On the diagram, sketch $y = (x+1)(x-3)^2$. Mark the points where the graph intersects the x-axis and the y-axis.
(b(ii))[3]
Write $(x+1)(x-3)^2$ as $ax^3 + bx^2 + cx + d$.
