What are the solutions to the equation 3 (x - 4) (x + 5) = 0?

Ox=-4 or x = 5

x = 3, x = 4, or x = - 5

x = 3, x = - 4, or x = 5

x = 4 or x = - 5

    x = 4 or x = - 5

    Step-by-step explanation:

    Solve for x over the real numbers:

    3 (x - 4) (x + 5) = 0

    Divide both sides by 3:

    (x - 4) (x + 5) = 0

    Split into two equations:

    x - 4 = 0 or x + 5 = 0

    Add 4 to both sides:

    x = 4 or x + 5 = 0

    Subtract 5 from both sides:

    Answer: x = 4 or x = - 5
