Question 58948
SO CLOSE!!!<br>

When you multiplied it out, you slyly worked out that i<sup>2</sup>=1 when it really equals -1!<Br>

So from (3+2i)(5-i) you foil to get 15-3i+10i-2i<sup>2</sup><br>

Since i<sup>2</sup>=-1, you can replace the i<sup>2</sup> with -1 to obtain:
15-3i+10i-2(-1) which equals 15-3i+10i<b>+</b>2 which simplifies to 17+7i.<br>

You've got the concept down though &#9786;
