Xsquared+1/20x-1/20 so i need that to be solved any way possible

Hallo ^_^

Quadratic Equation :
ax² + bx + c = 0

From the task :
x² + 1/20 x = 1/20

Switch sides :
x² + 1/20x - 1/20 = 0

Multiple each sides by 20
20(x² + 1/20x - 1/20) = 0(20)
⇒ 20x² + x - 1 = 0

From that :
a = 20, b = 1 and c = - 1

Solve x using quadratic formula :



Substitution using the formula :



Sorry for my bad english :)
