(x + (3 + 5i))*(x + (3+5i))
= x^2 + x(3+5i) + x(3+5i) + (3 + 5i)^2
= x^2 + 2x(3+5i) + 9 + 6(5i) + 25i^2
= x^2 + 6x +10xi + 9 + 30i - 25
= x^2 + 6x + 10xi + 30i - 16

Step-by-step explanation:
A proportion is a mathematical expression in which two ratios are shown to be equal.
Hence
is proportion .
it can be also written as a:b= c:d
The four part a,b,c,d can be divided into two groups
- means : b and c are means
- extremes: a and d are extremes
based on above discussion
in proportion 3/15=12/60
3 is in position of a
and
60 is in position of d
Thus, 3 and 60 are extremes in 3/15=12/60 proportion.
