Answer:

It's A.

Explanation:

5x2 + 60x = 0

5x is the GCF so:

5x(x + 12 ) = 0

5x = 0, x + 12 = 0

x =0, x = -12.

Answer:

The correct option is 1.

Explanation:

The given quadratic equation is


5x^2+60x=0

Taking out the common factors.


5x(x+12)=0

Using zero product property, equate each factor equal to 0.


5x=0\Rightarrow x=0


x+12=0\Rightarrow x=-12

The solutions of the given equations are x=0 and x=-12.

Therefore the correct option is 1.
