Expand by using the FOIL method.

First of all, you cannot evaluate the expression because it is an expression; you can only simplify it - that's what I'm going to tell you.

When simplifying two binomials, the easiest method is to FOIL the expand.

Calculator@TutorVista

$(~ 8 - 5 i) (~ 3 - 3 i)$ $(~8-5i)(~3-3i)$

$= 24 + 24 i + 15 i + 15 i^{2}$ $=24+24i+15i+15i^2$

$= 24 + 39 i + 15 i^{2}$ $=24+39i+15i^2$

I'm going to rearrange the expression so it is easier to read.

$= 15 i^{2} + 39 i + 24$ $=15i^2+39i+24$

That's it.

Hope this helps :)
