Step-by-step explanation:
given 
To rationalise multiply the numerator/denominator by the conjugate of the denominator
the conjugate of 3 + 7i is 3 - 7i, hence
distribute the numerator/denominator
= 
[ note that i² = - 1 ]
= 
= 
= 
+ 
i
= 
+ 
i ← in standard form
Step-by-step explanation:
You mean the answer is - 14
So - 14 + (-4) =
- 14 - 4 = 18
Answer: 3/16(x+4)(x-4)(x-2)
Step-by-step explanation:
