Question 240814
Since all the terms are being added or substracted across the parenthesis, we may remove the parentheses and combine like terms.
{{{(-4-3i)+(-6+8i)}}}
{{{-4-3i+-6+8i}}}
{{{-4-6-3i+8i}}}
{{{-10+5i}}}  <--- this is the simplified form of the expression
.
Remember "i" means the square root of -1 (an imaginary number).
