Question

Evaluate the expression and write the result in the form
a + bi.
(−6 + i) − (5 − 2i)

Answer 1

Just subtract them. You have -6 ones and you subtract 5 ones. How many do you have left?

You have 1 i and you subtract -2 i. How many do you have left?

Answer 2

are u saying its 11 and 3i

Answer 3

-6 - 5 = -11
1i - (-2)i = 3i

So

(-6 + i) - (5-2i)
= (-6 - 5) + (1i - (-2)i)
= -11 + 3i

Answer 4
