Answer:
One real root
Two imaginary roots
Step-by-step explanation:
Given polynomial,
Apply hit and trial method to find zero
This polynomial has one factor is
We can find another factor
Real root
is always positive so it have no real roots
Roots are imaginary
has one real root and two imaginary roots
Let g = original # of girls at the assembly.
Let w = # of boys at the assembly.
Equation of ratios:
w 3 boys
------- = ---- = --------------------------------------------
g-12 4 girls after 12 have left assembly
4w + 36
Cross-mult., 4w = 3g - 36, so 4w + 36 = 3g, and g = --------------- (answer)
4
This is "original # of girls at the assembly in terms of w, the # of boys at the assembly."
