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.
