Figure 3 shows a sketch of part of the curve C with equation Y=x(x+ 4)(x - 2)
The curve C crosses the x-axis at the origin and at the points A and B.
(a) Write down the x-coordinates of the points A and B.

Step-by-step explanation:

because The curve C crosses the x-axis at the origin and at the points A and B =>  the x coordinates of A and B are the solution of the equation:

 x(x + 4)(x - 2) = 0

<=> x = 0

      x = -4

      x = 2

because the x-coordinates of the points A and B aren't 0 and the x-coordinate

of A is a negative value

=>  the x-coordinate of  A is -4

the x-coordinate of B is 2
