In your problem a = 1, b = -4 and c = 5
so discriminant is -4
the discriminat is the value under the radical so if the number is negative there is no real solution.
if the number is 0 there is one solution
if the number is positive there are two solutions
For C highest to lowest
4/5, 3/4, 7/10, 1/2
For D
3/4, 17/24, 2/3, 7/12, 1/6
. Lisa's dog has 4 squeaky toys
. the squeaky toys are 2/3 of all the dog's toys
. let <em>x</em> be number of all dog toys
<em>make an equation</em>
(2/3)<em>x</em> = 4 <em>← solve</em>
x=6
<em>check</em>
2/3 × 6 = 4
<u>Lisa's Dog has 6 toys in all</u>
