Question 3992
A conjugate is the same expression as the original, but the sign in the middle changes:
{{{(-6+2i)*(-6-2i)}}}
Use the FOIL method to find the product of the two binomials:
{{{36+12i+(-12i)-4i^2}}}
Simplify:
{{{36-4i^2}}}
Since {{{i^2}}} is equal to -1, substitute the value of -1 where it says {{{i^2}}}.
{{{36-(-4)}}}
{{{36+4}}}
