Express in the form, a + bi: (-11 + 4i) + (6 + 8i)
Answer
a. -5 + 12i
b. 5 - 12i
c. -3 + 10i
d. -7 + 14i
just add them up as you're adding
(-11+4x) + (6+8x)
To express the given expression (-11 + 4i) + (6 + 8i) in the form a + bi, we need to combine the real parts and the imaginary parts separately.
First, let's combine the real parts (-11 and 6):
-11 + 6 = -5
Next, let's combine the imaginary parts (4i and 8i):
4i + 8i = 12i
Therefore, the expression (-11 + 4i) + (6 + 8i) can be expressed in the form a + bi as -5 + 12i.
So the correct answer is a. -5 + 12i.
