Question

Solve the quadratic equation 5x^2 + 75x = 0 by factoring out the GCF. (1 point)
The solutions are x = -15 and x = -5.
• The solutions are x = 0 and x = 15.
• The solutions are x = -15 and x = 0.
• The solutions are x = 0 andx = 5.

Answer 1

Factor out the GCF 5x: 5x(x + 15) = 0.
So x = 0 or x + 15 = 0 → x = -15.

Correct choice: The solutions are x = -15 and x = 0.
