We get rid of parentheses

3/2x-8x+5/2x+7=0

We multiply all the terms by the denominator


-8x*2x+7*2x+3+5=0

We add all the numbers together, and all the variables

-8x*2x+7*2x+8=0

Wy multiply elements

-16x^2+14x+8=0

a = -16; b = 14; c = +8;
Δ = b2-4ac
Δ = 142-4·(-16)·8
Δ = 708
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:

$\sqrt{\Delta}=\sqrt{708}=\sqrt{4*177}=\sqrt{4}*\sqrt{177}=2\sqrt{177}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(14)-2\sqrt{177}}{2*-16}=\frac{-14-2\sqrt{177}}{-32}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(14)+2\sqrt{177}}{2*-16}=\frac{-14+2\sqrt{177}}{-32}
