Answer:
x = (-5 ± √57) / 2
Step-by-step explanation:
x² = 8 − 5x
x² + 5x − 8 = 0
Solve with quadratic formula:
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -5 ± √(25 − 4(1)(-8)) ] / 2
x = (-5 ± √57) / 2
Answer:
There were 10 people in team one.
Step-by-step explanation:
Let x= team one.
Let y= team two
Because there four times less people in team one than in two we know that x=(1/4)y
After 6 people quit and 12 people transfer from team two, the two teams become equal. Therefore, x + 12 = y - 6 - 12.
You can then insert the initial equation for x into the second equation and know that there were 10 people in team one and 40 people in team two.
