x*1.32*(1.4)=71

Solution for x*1.32*(1.4)=71 equation:

x*1.32*(1.4)=71

We move all terms to the left:

x*1.32*(1.4)-(71)=0

Wy multiply elements

1.32x^2-71=0

a = 1.32; b = 0; c = -71;
Δ = b2-4ac
Δ = 02-4·1.32·(-71)
Δ = 374.88
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{-(0)-\sqrt{374.88}}{2*1.32}=\frac{0-\sqrt{374.88}}{2.64}
=-\frac{\sqrt{}}{2.64}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{374.88}}{2*1.32}=\frac{0+\sqrt{374.88}}{2.64}
=\frac{\sqrt{}}{2.64}
