Example Question #1 : Algebra 1
What is the solution of 3x = 9?
–6
–3
3
1/3
6
3
When solving a one step equation like this, we do the inverse operation to isolate the variable. In this case, we have 3x = 9, so we divide both sides by 3 to get x = 3.
3x = 9
(3x)/3 = (9)/3
x = 3

A complex number in its standard form is of the form: , where stands for the real part and stands for the imaginary part. The symbol stands for .
The imaginary part is .
Example Question #2 : Algebra 1
Find the conjugate of .
The conjugate is so that when is multiplied by its conjugate we get
Since
we get
.
Example Question #3 : Algebra 1
Identify the real part of .
A complex number in its standard form is of the form: , where stands for the real part and stands for the imaginary part. The symbol stands for .
The real part is 0.
In this problem there is no real part. Hence the real part equals 0.
