Simplify the expression . explain

1/2 + 5/2 i

Step-by-step explanation:

(-5+i)         i

*

2i             i

cannot have i in the denominator so we multiply by i

(-5+i)         i             -5i + i^2

*  =

2i             i              +2i^2

remember i^2 = -1

     -5i + -1        -1 -5i

= =

    +2(-1)                        -2

get rid of the negative in the denominator by multiplying the top and bottom by -1

    (-1 -5i) * -1

=

          -2*(-1)

    (1 +5i)

=   =   1/2 + 5/2 i

          2

answer is x<

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
