(6-3i)(5+9i)=0
We add all the numbers together, and all the variables
(-3i+6)(9i+5)=0
We multiply parentheses ..
(-27i^2-15i+54i+30)=0
We get rid of parentheses
-27i^2-15i+54i+30=0
We add all the numbers together, and all the variables
-27i^2+39i+30=0
a = -27; b = 39; c = +30;
Δ = b2-4ac
Δ = 392-4·(-27)·30
Δ = 4761
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$i_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$i_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{4761}=69$$i_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(39)-69}{2*-27}=\frac{-108}{-54} =+2 $$i_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(39)+69}{2*-27}=\frac{30}{-54} =-5/9 $
