2 plus 4i - 7 plus 4i?

(2 + 4i) - (7 + 4i) = -5 2 + 4i - 7 + 4i = -5 + 8i


What is the conjugate of -6 plus 4i?

-6-4i.


What is the sum of two complex conjugate number?

Since the imaginary parts cancel, and the real parts are the same, the sum is twice the real part of any of the numbers. For example, (5 + 4i) + (5 - 4i) = 5 + 5 + 4i - 4i = 10.


What is the additive inverse of 6 plus 4i?

The additive inverse of 6+4i is -6-4i since their sum is 0. It is analogous to real numbers where the additive inverse of 6 is -6 since 6+-6 =6-6=0 In the case of complex numbers, we add them by adding the real parts and then adding the imaginary parts. So to find the complex additive inverse of a+bi, we find the inverse of a which is -a and of bi which is -bi and so the additive inverse is -a-bi


What is conjugate of 4i open bracket -2 -3i close bracket?

4i(-2 -3i) = 4i×-2 - 4i×-3i = -8i -12i² = -8i + 12 = 12 -8i → the conjugate is 12 + 8i


How do you solve 9 plus 4i quantity squared?

When the sum of the complex numbers 3 plus 2I and 6 - 4I is graphed in which quadrant does it lie?

3+2i + 6-4i = 9-2i The real part of this number is positive, therefore it lies in Q1 or Q4. The imaginary part is negative, therefore it is in Q3 or Q4. Q4 is the common possibility, therefore 9-2i is in Q4.


Can someone translate this the sum of a number and ten is the difference of -6 and -6 increased by the sum of -1 and -1?

Do this in reverse. The sum of -1 and -1 is -1+-1=-2 The difference of -6 and -6 is -6-(-6)=-6+6=0 0 increased by -2 is 0+-2=-2 The sum of 10 and -2 is 10+-2=8 Translation: 8
