Answer:
x^3 - 5 x^2 + 2 x + 8 = 0
Step-by-step explanation:
Solve for x over the real numbers:
x^3 - 5 x^2 + 2 x + 8 = 0
The left hand side factors into a product with three terms:
(x - 4) (x - 2) (x + 1) = 0
Split into three equations:
x - 4 = 0 or x - 2 = 0 or x + 1 = 0
Add 4 to both sides:
x = 4 or x - 2 = 0 or x + 1 = 0
Add 2 to both sides:
x = 4 or x = 2 or x + 1 = 0
Subtract 1 from both sides:
Answer: x = 4 or x = 2 or x = -1
The symbols, you mean? Those are called "parentheses".
