Ok this is something i learned few years ago and I am a bit rusty.
So i have to find the absolute value of:
[tex]\frac{1 - 2i}{3 + 4i}[/tex] + [tex]\frac{i - 4}{6i - 8}[/tex]
So first i add the two fractions and i get:
[tex]\frac{(1 - 2i)(6i - 8) + (i - 4)(3 + 4i)}{(3 + 4i)(6i - 8)}[/tex]
Next i simplify and then i find the absolute value of the complex numbers above and below
Is this correct, because i have forgoten.
