Answer:
x = -3 or x = -5/3
Step-by-step explanation:
Solve for x over the real numbers:
(x + 3) (3 x + 5) = 0
Split into two equations:
x + 3 = 0 or 3 x + 5 = 0
Subtract 3 from both sides:
x = -3 or 3 x + 5 = 0
Subtract 5 from both sides:
x = -3 or 3 x = -5
Divide both sides by 3:
Answer: x = -3 or x = -5/3
