16x/24x^2+(-9x)/24x^2-26=0

We multiply all the terms by the denominator


16x+(-9x)-26*24x^2=0

Wy multiply elements

-624x^2+16x+(-9x)=0

We get rid of parentheses

-624x^2+16x-9x=0

We add all the numbers together, and all the variables

-624x^2+7x=0

a = -624; b = 7; c = 0;
Δ = b2-4ac
Δ = 72-4·(-624)·0
Δ = 49
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{49}=7$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7)-7}{2*-624}=\frac{-14}{-1248}
=7/624
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+7}{2*-624}=\frac{0}{-1248}
=0
