So the question looks like $3x ^{2}-21x-54$? Correct?

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

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

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

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

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

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

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

$$\color{blue}{\text{Originally Posted by}}$$ @bryce0706 X-7x-18 $$\color{blue}{\text{End of Quote}}$$ 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
