Solution for c=5x^2+12x+c equation:


Simplifying
c = 5x2 + 12x + c

Reorder the terms:
c = c + 12x + 5x2

Add '-1c' to each side of the equation.
c + -1c = c + 12x + -1c + 5x2

Combine like terms: c + -1c = 0
0 = c + 12x + -1c + 5x2

Reorder the terms:
0 = c + -1c + 12x + 5x2

Combine like terms: c + -1c = 0
0 = 0 + 12x + 5x2
0 = 12x + 5x2

Solving
0 = 12x + 5x2

Solving for variable 'x'.
Remove the zero:
-12x + -5x2 = 12x + 5x2 + -12x + -5x2

Reorder the terms:
-12x + -5x2 = 12x + -12x + 5x2 + -5x2

Combine like terms: 12x + -12x = 0
-12x + -5x2 = 0 + 5x2 + -5x2
-12x + -5x2 = 5x2 + -5x2

Combine like terms: 5x2 + -5x2 = 0
-12x + -5x2 = 0

Factor out the Greatest Common Factor (GCF), '-1x'.
-1x(12 + 5x) = 0
