(c + di)^2 = c^2 + 2cdi + (di)^2
= c^2 + 2cdi - d^2
= c^2 - d^2 + 2cdi
The real part is c^2 - d^2. The imaginary part is cdi.
Since c and d are nonzero real numbers, the product cd is also nonzero and real. Even if c and d are equal, and the real part c^2 - d^2 becomes zero, the imaginary part, cdi will always have a nonzero coefficient (cd). Therefore, the imaginary part is always there.
Answer:
x >-8
Step-by-step explanation:
22−2x<38
Subtract 22 from each side
22-22−2x<38-22
-2x < 16
Divide each side by -2, remembering to flip the inequality
-2x/-2 > 16/-2
x >-8
Are u supposed to finish the sentence or..? Cause i dont get the question
Answer:
1.083
Step-by-step explanation:
2.75-(9+6)/9
Answer:
I got .96
Step-by-step explanation:
2+23 is 25. 25 devided by 12 is .48. Times that by 2 and you get . 96. clearly that's not an option though so I'm not sure. sorry. did you make a typo by any chance?
