X(3.35)x=1.8

Solution for X(3.35)x=1.8 equation:

X(3.35)X=1.8

We move all terms to the left:

X(3.35)X-(1.8)=0

We add all the numbers together, and all the variables

X(3.35)X-1.8=0

We multiply parentheses

3.35X^2-1.8=0

a = 3.35; b = 0; c = -1.8;
Δ = b2-4ac
Δ = 02-4·3.35·(-1.8)
Δ = 24.12
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{24.12}}{2*3.35}=\frac{0-\sqrt{24.12}}{6.7}
=-\frac{\sqrt{}}{6.7}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{24.12}}{2*3.35}=\frac{0+\sqrt{24.12}}{6.7}
=\frac{\sqrt{}}{6.7}
