welcome

anonymous · Answer

Okay.  What is one thing that you can factor out of all 3 parts of the equation?

anonymous · Answer

3

anonymous · Answer

Yep.  So what are you left with once you factor that out?

anonymous · Answer

X-7x-18

anonymous · Answer

Yep.  Does that factor?

anonymous · Answer

Like my teacher wants me to factor it like. for example x squared minus 7x minus 18. like the factored would be (×-9)(×+2)

anonymous · Answer

$$\frac{1}{3} \left(3 x^2-21 x-54\right)=x^2-7 x-18 $$

triciaal · Answer

**x^2 -7x-18
the first term is x^2

anonymous · Answer

Yep!!  So you're answers would be?

anonymous · Answer

Thats what im asking it has a coefficiant and changes it completely how to do it

anonymous · Answer

like instead of the first term having a coefficient of one it has one of 3 and changes how to do the whole distributive property on it

3 is common factor so u r left with (x^2 -7x -18)
find two number  if you multiply them you should product of AC and if you add or subtract them you should get middle term
