-3/4a-1/2a-1=0

We calculate fractions


(-6a)/8a^2+(-4a)/8a^2-1=0

We multiply all the terms by the denominator


(-6a)+(-4a)-1*8a^2=0

Wy multiply elements

-8a^2+(-6a)+(-4a)=0

We get rid of parentheses

-8a^2-6a-4a=0

We add all the numbers together, and all the variables

-8a^2-10a=0

a = -8; b = -10; c = 0;
Δ = b2-4ac
Δ = -102-4·(-8)·0
Δ = 100
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{100}=10$
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-10)-10}{2*-8}=\frac{0}{-16}
=0
$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-10)+10}{2*-8}=\frac{20}{-16}
=-1+1/4
