x+p+z+f+4 = 6
6/4 = x
p+z=f•f
p = ?
x = ?
z = ?
f = ?
or not enough info ?
x+p+z+f+4 = 6
6/4 = x
p+z=f•f
x+p+z+f+4 = 6
6/4 + f^2 + f + 4=6
f^2 + f=6-4-6/4
f^2 + f=1/2
Solve for f:
f^2+f = 1/2
Add 1/4 to both sides:
f^2+f+1/4 = 3/4
Write the left hand side as a square:
(f+1/2)^2 = 3/4
Take the square root of both sides:
f+1/2 = sqrt(3)/2 or f+1/2 = -sqrt(3)/2
Subtract 1/2 from both sides:
f = sqrt(3)/2-1/2 or f+1/2 = -sqrt(3)/2
Subtract 1/2 from both sides:
Answer: | f = sqrt(3)/2-1/2 or f = -1/2-sqrt(3)/2 f=.366 or f=-1.366
x+p+z+f+4 = 6
x=6/4
p=.133956
z=.133956
f=.366
THERE COULD BE OTHER SOLUTIONS!!!!!!.
