<span>apples = (50+x)(800-10x)
= (40000-500x+800x-10x^2)
= -10x^2 +300x + 40000
Max occurs when x = -b/(2a) = -30/(-2) = 15
= -x^2 + 30x + 4000
Max occurs when x = -b/(2a) = -30/(-2) = 15
15 trees should be added</span>
It's 6:1. Since you divide the sides corresponding each other.

Answer:
x = 8 + sqrt(3)/2 or x = 8 - sqrt(3)/2
Step-by-step explanation by completing the square:
Solve for x:
3 - 4 (x - 8)^2 = 0
Subtract 3 from both sides:
-4 (x - 8)^2 = -3
Divide both sides by -4:
(x - 8)^2 = 3/4
Take the square root of both sides:
x - 8 = sqrt(3)/2 or x - 8 = -sqrt(3)/2
Add 8 to both sides:
x = 8 + sqrt(3)/2 or x - 8 = -sqrt(3)/2
Add 8 to both sides:
Answer: x = 8 + sqrt(3)/2 or x = 8 - sqrt(3)/2
