rearrange into quadratic form ax^2+bx+c=0. . 0.20= x^2/(25-x). . where a=1, and identify values of b and c
vivado [14]
Simplifying 0.20 = x^2 / (25 - x):

Multiply both sides by (25 - x)
0.20(25 - x) = x^2

Distributing 0.20:
5 - 0.20x = x^2

Placing all equations on to one side:
x^2 + 0.20x - 5 = 0

Where:
a = 1
b = 0.20
c = -5
