(6,3x)*(6,5x)=14,8

Solution for (6,3x)*(6,5x)=14,8 equation:

(6.3x)(6.5x)=14.8

We move all terms to the left:

(6.3x)(6.5x)-(14.8)=0

We add all the numbers together, and all the variables

(+6.3x)(+6.5x)-(14.8)=0

We add all the numbers together, and all the variables

(+6.3x)(+6.5x)-14.8=0

We multiply parentheses ..

(+36x^2)-14.8=0

We get rid of parentheses

36x^2-14.8=0

a = 36; b = 0; c = -14.8;
Δ = b2-4ac
Δ = 02-4·36·(-14.8)
Δ = 2131.2
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{2131.2}}{2*36}=\frac{0-\sqrt{2131.2}}{72}
=-\frac{\sqrt{}}{72}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{2131.2}}{2*36}=\frac{0+\sqrt{2131.2}}{72}
=\frac{\sqrt{}}{72}
