We calculate fractions


10x/15x^2+(-9x)/15x^2+1-2=0

We add all the numbers together, and all the variables

10x/15x^2+(-9x)/15x^2-1=0

We multiply all the terms by the denominator


10x+(-9x)-1*15x^2=0

Wy multiply elements

-15x^2+10x+(-9x)=0

We get rid of parentheses

-15x^2+10x-9x=0

We add all the numbers together, and all the variables

-15x^2+x=0

a = -15; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·(-15)·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*-15}=\frac{-2}{-30}
=1/15
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*-15}=\frac{0}{-30}
=0
