How do you solve complex fraction?
this is a very good question. lets solve (2+3i)/(4-2i). we want to make 4-2i real by multiplying it by the conjugate, or 4+2i (4-2i)(4+2i)=16-8i+8i+4=20, now we have (2+3i)/20 0r 1/10 + 3i/20 notice that -2i times 2i = -4i^2 =-4 times -1 = 4
What is the answer if you Find all the roots of the equation x4 - 2x3 plus 14x2 - 18x plus 45 0 given that 1 plus 2i is one of its roots.?
The four roots are:1 + 2i, 1 - 2i, 3i and -3i.
How do you find areas of a complex square?
if you mean both dimensions are complex numbers, then you use foil. Example (1+i)(1+2i)= 1 + 3i - 2 (since i2 = -1) -1+3i that's a rectangle but you should understand if your in a class with complex #
How do you read two complex numbers and perform addition and subtraction?
To add complex numbers, the real parts and the imaginary parts are added separately. For example, to add (3 + 3i) + (5 - 2i), the result is (3+5) + (3-2)i = 8+i. Subtraction is quite similar - you subtract the real and the imaginary parts separately. For example, (3 + 3i) - (5 - 2i) = (3-5) + (3 - -2)i = -2+5i.
What is the cartesian form of this complex no 1 plus i cube?
(1+i)3 = 1 + 3i - 3 - i = -2 + 2i This is a complex number, and therefore cannot be plotted on a Cartesian plane.
Find the sum of negative 2 plus 3i and negative1 minus 2i?
(-2 + 3i) + (-1 - 2i) = -2 + 3i - 1 - 2i = -2 - 1 + 3i - 2i = -3 + i

How do you do the math problem (4-3i)(5 2i)?
To multiply complex numbers you can use the same FOIL rule that you use for multiplying binomials (First, Inside, Outside, Last).(4 - 3i)(5 + 2i) = (4)(5) +(4)(2i) - (3i)(5) - (3i)(2i) = 20 + 8i-15i - 6(i)^2= 20 -7i - 6(-1) = 20 + 6 -7i = 26 -7i.

The four roots are:1 + 2i, 1 - 2i, 3i and -3i.
What are orthogonal pairs a 3i 2j b you j c 2i-3j d 7i j?
3i+2j)*(2i-3j)=0 bcz dot product is zero.

Solve the expression 3i 5-2i?
Expressions cannot be solved. Only equations or inequalities may be solved. Also, there is no symbol between 3i and 5.
Which of these are complex numbers 5 3i 1 2i?
All of them. Real numbers are a subset of complex numbers.
How do you subtract imaginary numbers?
When adding and subtracting complex numbers, you can treat the "i" as any variable. For example, 5i + 3i = 8i, 5i -3i = 2i, etc.; (2 + 5i) - (3 - 3i) = (2 - 3) + (5 + 3)i = -1 + 8i.
How do you simplify the expression 3i x -4i?

Let A equals 1 plus 2i and let C equals 5 plus 5i what is A-C?
-4-3i
What is the answer to 5 plus 2i2-3i equals zero?
5 + 2 i 2 -3 i = 0(i + 1)(2i - 5) = 0(i + 1) = 0, so, i = -1and(2i - 5) = 0, so, i = 5/2i two values are: -1 and 5/2
