I used synthetic division on the first one cuz I could and got that D is the answer for that one (#3); the next one I used long division and got C. Learn how to do this because it's a method of factoring and factoring is everywhere...it's just as important as being able to solve equations.
Well its going to be kinda a lot to explain but maybe you give me a call I can kinda explain it but typing it will be a lot
irrational
irrational because it keeps on going on forever!
Answer:
B. x = 5 and y = -13
Step-by-step explanation:
Equating real parts, we have ...
... x + 4 = 9
... x = 9 - 4 . . . . subtract 4
... x = 5
___
Equating imaginary parts, we have ...
... yi +9i = -4i
... yi = -4i -9i = -13i . . . . subtract 9i
... y = -13 . . . . . . . . . . . divide by i
