how do i solve: -5n(n+3)=0 by using the zero-product property?

Question

anonymous · Answer

-5n=0
n+3=0

anonymous · Answer

n=0, n=-3

anonymous · Answer

-5n (n+ 3) =0
-5(2 n) + -15n= 0
-10n + -15n +0
-25n=0
+25   +25
n=25

ill help; but save the vulgarity for a different forum please.  we are trying to keep this a family friendly environment....

amistre64 · Answer

sometimes is my best guess

amistre64 · Answer

it depends on the base being used.

If the base is between 0 and 1; it increases as x gets small

if its greater than 1; it decreases as x gets small

amistre64 · Answer

well, same principle; different x values direction :)

amistre64 · Answer

2^x increases as x gets bigger

(1/2)^x  decreases as x gets bigger, so sometimes

macy · Answer

yeah that was my guess too. thanks
