Discriminant = b^2 - 4ac, where a, b and c come from the form of the quadratic equation as ax^2 + bx + c
Discriminant = (4)^2 - 4(1)(5)
= 16 - 20
= -4
-4 < 0, therefor there are no roots
(If the discriminant = 0, then there is one root
If the discriminant > 0, there are two roots, and if it is a perfect square (eg. 4, 9, 16, etc.) then there are two rational roots
If the discriminant < 0, there are no roots)
Answer:
$25.44
Step-by-step explanation:
35% of $39 is $13.65
$39-$13.65=$25.44
Answer:
Step-by-step explanation:
2 cups=8/4 1/2=2/4 1/8=0.5/4
8/4-1/4=7/4
7/4-2/4=5/4
5/4-0.5/4=4.5/4
Answer:1 0.5/4 cups
