Answer:
x = 3 or x = -5
Step-by-step explanation:
Solve for x over the real numbers:
-(x + 5) (x - 3)^3 = 0
Multiply both sides by -1:
(x - 3)^3 (x + 5) = 0
Split into two equations:
(x - 3)^3 = 0 or x + 5 = 0
Take cube roots of both sides:
x - 3 = 0 or x + 5 = 0
Add 3 to both sides:
x = 3 or x + 5 = 0
Subtract 5 from both sides:
Answer: x = 3 or x = -5
