Question

simplify(-1+6i) + (-4 + 2i)

Answer 1

well you know that i^2 = -1 right?

Answer 2

just foil like how you've done it before

Answer 3

can you show me an example with a similar problem?

Answer 4

ok well its like this
Ex: (-x + 2)(-x + 2)
x^2 - 2x -2x + 4
x^2 - 4x + 4

Answer 5

the i's are confusing me

Answer 6

and for your question its the same steps

Answer 7

5 + 8i?

Answer 8

ok ill show you step by step
First, you must write the equation on paper (-1+6i)(-4 + 2i)
Then, you just foil like how i showed you as an example 4 - 2i - 24i + 12i^2
Finally, you add and subtract like terms 4 - 26i + 12i^2
ans i told you i^2 = -1
4 - 26i -12
-8 - 26i

Answer 9

(-1+6i) + (-4 + 2i)
-1 + 6i -4 +2i
-5 +8i
now rationalize it by -5 -8i
and get the answer

Answer 10

or that

Answer 11

thanks
