just distribute the negative sign to the second bracket
LynFran
  • LynFran
so we have 5-2i-1-3i
LynFran
  • LynFran
now group like term and simplify
LynFran
  • LynFran
and no its not A

I only thought it was A because if you do 5-2=4 and 1+3=4
LynFran
  • LynFran
but 5-2i arent like term... they can not =4
LynFran
  • LynFran
5-2i-1-3i = 5-1 are like term and -2i-3i are like terms
anonymous
  • anonymous
so it would be 4 and -5
LynFran

4-5i

Which expression is equal to -2i(4-i) A)8-2i B)-2-8i C)-8-2i D)2-8i
LynFran
  • LynFran
distribute the -2i to the bracket
anonymous
  • anonymous
you do 2x4=8i so it would be 2-8i??
LynFran
  • LynFran
and none of those expressions would equal to that you shd get -2i*4+2i^2 -8i+2i^2
anonymous
  • anonymous
I'm a bet confuse on what should I do??
LynFran
  • LynFran
-2i multiple to 4 = -8i and -2i multiply to -i =2i^2
LynFran
  • LynFran
r u sure u wrote the expression correctly??
