=(3A+5)2A
We move all terms to the left:
-((3A+5)2A)=0
We calculate terms in parentheses: -((3A+5)2A), so:
(3A+5)2A
We multiply parentheses
6A^2+10A
Back to the equation:
-(6A^2+10A)
We get rid of parentheses
-6A^2-10A=0
a = -6; b = -10; c = 0;
Δ = b2-4ac
Δ = -102-4·(-6)·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*-6}=\frac{0}{-12} =0 $
$A_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-10)+10}{2*-6}=\frac{20}{-12} =-1+2/3 $
