ANSWER

EXPLANATION
The given parabola has directrix x=2.
This implies that, the parabola is opens in the direction of the negative x-axis because it must open in a negative direction to the directrix.
The equation of such parabola is of the form:

where (h,k)=(-5,8) is the vertex.


But the parabola opens to the left.
p=-7
The equation now becomes

Answer:
x = ±10
Step-by-step explanation:
4x² - 400 = 0
Add 400 to both sides
4x² = 400
Divide both sides by 4
x² = 100
Take the square root of both sides
x = ±10
