We calculate fractions


(-6x)/18x^2+(-15x)/18x^2-13+34=0

We add all the numbers together, and all the variables

(-6x)/18x^2+(-15x)/18x^2+21=0

We multiply all the terms by the denominator


(-6x)+(-15x)+21*18x^2=0

Wy multiply elements

378x^2+(-6x)+(-15x)=0

We get rid of parentheses

378x^2-6x-15x=0

We add all the numbers together, and all the variables

378x^2-21x=0

a = 378; b = -21; c = 0;
Δ = b2-4ac
Δ = -212-4·378·0
Δ = 441
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{441}=21$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-21)-21}{2*378}=\frac{0}{756}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-21)+21}{2*378}=\frac{42}{756}
=1/18
