In a quadratic equation
q(x) = ax^2 + bx + c
The discriminant is = b^2 - 4ac
We have that discriminant = 3
If
b^2 - 4ac > 0, then the roots are real.
If
b^2 - 4ac < 0 then the roots are imaginary
<span>In
this problem b^2 - 4ac > 0 3 > 0 </span>
then
the two roots must be real
Answer: 41.6%
Step-by-step explanation:
You divide the amount of trees 40ft or taller (10) by the total number of trees (24) so 10/24 = .416 (41.6%)
The extraneous root is
x = 2
