Hey there!
In order to find the additive inverse of any number, regardless if it is real or not, you can simply multiply the number by -1 or negate it.
This should look like this:
-(6-3i)
=-6+3i
Therefore, the additive inverse of 6-3i is -6+3i.
**Note: Keep in mind, when the additive inverse of a number is added to the number, the number equals 0:
(6-3i)+(-6+3i)=0
Hope this helps and have a marvelous day! :)
If we observe closely the given, we can note that the
terms given are perfect cubes. That is,
<span> x^3 is
cube of x and</span>
<span> 343 is
cube of 7</span>
Hence, the expression is the sum of two cubes. For the
sum of cubes, we follow the following rule for the factoring:
<span> a^3 + b^3 = (a +
b)(a^2 – ab + b^2)</span>
Applying the rule to the given, the factors would be:
<span> X^3 + 373 = (x +
7)(x^2 – 7x + 49)</span>
