x!=0/3

x!=0

x∈R


We calculate fractions


9x/3x^2+(-4x)/3x^2-10=0

We multiply all the terms by the denominator


9x+(-4x)-10*3x^2=0

Wy multiply elements

-30x^2+9x+(-4x)=0

We get rid of parentheses

-30x^2+9x-4x=0

We add all the numbers together, and all the variables

-30x^2+5x=0

a = -30; b = 5; c = 0;
Δ = b2-4ac
Δ = 52-4·(-30)·0
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-5}{2*-30}=\frac{-10}{-60}
=1/6
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+5}{2*-30}=\frac{0}{-60}
=0
