-20x2 = 36x
Solving
-20x2 = 36x
Solving for variable 'x'.
Reorder the terms:
-36x + -20x2 = 36x + -36x
Combine like terms: 36x + -36x = 0
-36x + -20x2 = 0
Factor out the Greatest Common Factor (GCF), '-4x'.
-4x(9 + 5x) = 0
-4.

divide both sides by the 25
x² = 16/25
take the square root of both sides
x = √(16/25) = √16/√25 = 4/5
