x^2-4.4x+2.7=0

Solution for x^2-4.4x+2.7=0 equation:

x^2-4.4x+2.7=0

a = 1; b = -4.4; c = +2.7;
Δ = b2-4ac
Δ = -4.42-4·1·2.7
Δ = 8.56
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-4.4)-\sqrt{8.56}}{2*1}=\frac{4.4-\sqrt{8.56}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4.4)+\sqrt{8.56}}{2*1}=\frac{4.4+\sqrt{8.56}}{2}
