Solution for f^2-27f=0 equation: 



f^2-27f=0

a = 1; b = -27; c = 0;
Δ = b2-4ac
Δ = -272-4·1·0
Δ = 729
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$f_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$f_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{729}=27$


$f_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-27)-27}{2*1}=\frac{0}{2}
=0
$


$f_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-27)+27}{2*1}=\frac{54}{2}
=27
$
