u need help

Answer 2

yes actually

Answer 3

Simplify the given expression:

(−5 + 3i) • (1 − 2i)

I've been having trouble with these... I use FOIL and then combine like terms but the answer I come up with is never an option. These are my four options the closest one to my answer is the second one.
−5 − 6i

1 + 13i

2 + i

4 − 5i

Answer 4

@abbyrose0105 try simplifying this

Answer 5

@abbyrose0105 simplify −6x2+13x−5

Answer 6

is that -6x^2? is the x squared?

Answer 7

yes

Answer 8

x=i srry

Answer 9

so x is an imaginary number?

Answer 10

kinda yes

Answer 11

ok I'll try

Answer 12

alright

Answer 13

It should be 1+13i

Answer 14

If x=i then you can substitute i for x making the problem look like this: -6i^2+13i-5
i^2=-1 so that would make -6(-1)=6, 6-5=1 and 1+13i cannot be added because 13i and 1 are considered different numbers

Answer 15

good job
