Plz help I dont get it and Can you show me the work so I can understand it

campbell_st · Answer

can you check the 1st question is correct... 

otherwise it won't factor... and will need the general quadratic formula to solve it

anonymous · Answer

x=-3x^2-12x-9

anonymous · Answer

would that help?

campbell_st · Answer

well hopefully its 

y = -3x^2 - 12x - 9

take out -3 as a common factor

y = -3(x^2 + 4x + 3)

factor the quadratic and its 

y = -3(x + 3)(x +1)

hope it helps
