Question

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

Answer 1

x = 4 or x = -5

Explanation:

Answer 2

x = 4 or x = -5

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
