The expression which is the result of subtracting the complex number (Z2-3i) from another complex number (Z1 + 2) is 9-2i.
How to calculate complex number from graph?
To find the value of a complex number from the graph, follow the steps below.
- On the graph where x-axis represents the real line, the distance of the point give the real number.
- On the graph where y-axis represents the imaginary line, the distance of the point give the imaginary number, which is written with complex number i.
The point Z1 is 3 units right and 4 units down from the origin point. Thus, the complex number which represent it is,
[tex]Z_1=3-4i[/tex]
The point Z2 is 4 units left and 1 units up from the origin point. Thus, the complex number which represent it is,
[tex]Z_2=-4+1i[/tex]
The expression which is the result of subtracting (Z2-3i) from (Z1 + 2) is,
[tex](Z_1 + 2)-(Z_2-3i)\\(3-4i + 2)-(-4+i-3i)\\3-4i + 2+4-i+3i\\9-2i[/tex]
Hence, the expression which is the result of subtracting the complex number (Z2-3i) from another complex number (Z1 + 2) is 9-2i.
