Multiply (x + 3) (3x + 5) =

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
