Work Step by Step

We know that $i=\sqrt{-1}$. We also know that standard form is $a\pm bi$, where a and b are real numbers. Thus, simplifying the equation, we find: $$\left(a+bi\right)\left(c+di\right)=\left(ac-bd\right)+\left(ad+bc\right)i \\ \left(4\cdot \:6-\left(-2\right)\cdot \:5\right)+\left(4\cdot \:5+\left(-2\right)\cdot \:6\right)i \\ 34+8i$$
