Answer:
There are two zeros. The intercepts are -2 and -4
Step-by-step explanation:
The zeros of a parabola are the points where the parabola intersects with the x axis. In other words, they are when the y value equals zero.
In this case, we see that the parabola intersects the x axis at two different points. Those points are (0, -2) and (0, -4)
-2a²
The question is 2a × -a
This means 2a(-a)
= -2×(a×a)
=-2(a²)
=-2a²

200 x 0.3
= 60
200 - 60
= 140
