Answer:
646 child tickets are sold
Step-by-step explanation:
Let c represent the number of child tickets sold. Then (c-186) is the number of student tickets sold, and (c+234) is the number of adult tickets sold. The total number sold is ...
(c -186) + c + (c+234) = 1986
3c +48 = 1986 . . . simplify
c + 16 = 662 . . . . divide by 3
c = 646 . . . . . . . . . subtract 16
The number of child tickets sold is 646.
Answer:
Let y=x² . Then:
x4−10x2+9=y2−10y+9
y²-10y+9=(y-9)(y-1)
Substitute x² for y:
x4−10x2+9=(x2−9)(x2−1)
x²-9=(x+3)(x-3)
x²-1=(x+1)(x-1)
x4−10x2+9=(x+3)(x−3)(x+1)(x−1)
