The discriminate is b^2 - 4*a*c
The general equation for a quadratic is ax^2 + bx + c
In this equation's case
a = 1
b= -5
c = - 3
Solve
(-5)^2 - 4*(1)*(-3)
25 - (-12)
25 + 12
37
Note
Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.

Answer:
4 kg : 12 kg : 20 kg
Step-by-step explanation:
The total number of "ratio units" is 1+3+5 = 9, so each of them represents ...
(36 kg)/9 = 4 kg
Multiplying the given ratio by 4 kg will show the appropriate division:
1(4 kg) : 3(4 kg) : 5(4 kg) = 4 kg : 12 kg : 20 kg
Answer:
1/10
Step-by-step explanation:
