5x-6/2x+1=0

Solution for 5x-6/2x+1=0 equation:

5x-6/2x+1=0


Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R


We multiply all the terms by the denominator


5x*2x+1*2x-6=0

Wy multiply elements

10x^2+2x-6=0

a = 10; b = 2; c = -6;
Δ = b2-4ac
Δ = 22-4·10·(-6)
Δ = 244
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{244}=\sqrt{4*61}=\sqrt{4}*\sqrt{61}=2\sqrt{61}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{61}}{2*10}=\frac{-2-2\sqrt{61}}{20}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{61}}{2*10}=\frac{-2+2\sqrt{61}}{20}
