Question

Evaluate the expression (-5 - 9i)(-6 - 6i), and write your answer in the form a + bi. a = ___ and b = ___

SnapAndSolve AI · Accepted Answer

First, expand the expression using the distributive property (FOIL method):

Combine the real and imaginary parts:

Real part: 30 - 54 = -24

Imaginary part: 30i + 54i = 84i

So, the expression in the form a + bi is:

a = -24 and b = 84

Evaluate the expression (-5 - 9i)(-6 - 6i), and write your answer in the form a + bi. a = _ and b = _
