Answer:

#n=-1 or n=0#

Explanation:

#2n(3n+3)=0# => in factored form use:
Zero Product Property
If #ab=0#, then either #a=0# or #b=0#, or both #a# & #b# are #0#:
therefore:
#2n=0#
#n=0#
Or:
#3n+3=0#
#3n=-3#
#n=-1#

Answer:

#n=0" or "n=-1#

Explanation:

When we have a #color(blue)"product of factors equal to zero"#

#"That is "axxb=0" then"#

• a = 0 or b = 0 or both a and b equal zero.

#rArr2n(3n+3)=0#

#•"solve "2n=0rArrn=0#

#•"solve "3n+3=0#

subtract 3 from both sides.

#3ncancel(+3)cancel(-3)=0-3#

#rArr3n=-3#

divide both sides by 3

#(cancel(3) n)/cancel(3)=(-3)/3#

#rArrn=-1#

#rArrn=0" or "n=-1" are the solutions"#
