X^2 - 25 is a difference of squares which has a special factorization.
In general, a^2 - b^2 = (a + b)(a - b)
x^2 - 25 = 0
(x + 5)(x - 5) = 0
x + 5 = 0 or x - 5 = 0
x = -5 or x = 5
Answer:
8-3i
Step-by-step explanation:
The complex additive inverse is the number we need to add so that we get zero. It is the negative of the number.
a + bi is –(a + bi) = –a – bi.
a+bi + (-a+-bi) = a-a + bi-bi = 0
The complex additive invers of -8+3i is
-(-8+3i)
Distribute the negative
8 -3i
