We multiply all the terms by the denominator


b*13.24.25-13.3-(9.7)*13.24.25=0

We add all the numbers together, and all the variables

b*13.24.25-45.407=0

Wy multiply elements

13b^2-45.407=0

a = 13; b = 0; c = -45.407;
Δ = b2-4ac
Δ = 02-4·13·(-45.407)
Δ = 2361.164
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{2361.164}}{2*13}=\frac{0-\sqrt{2361.164}}{26}
=-\frac{\sqrt{}}{26}
$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{2361.164}}{2*13}=\frac{0+\sqrt{2361.164}}{26}
=\frac{\sqrt{}}{26}
