-x^2+9x-18=

supie:

So we have to factor them...\[−x^2+9x−18=\]\[(−x+3)(x−6)\] Yes?

dontsaymyname:

Yes

dontsaymyname:

I believe so

jackiejackiejack:

"should we" lmao

dontsaymyname:

XDD

supie:

Ok well \[(−x+3)(x−6)=\]\[(−x+3)(x+−6)=\]\[(−x)(x)+(−x)(−6)+(3)(x)+(3)(−6)=\]\[−x^2+6x+3x−18\]\[−x^2+9x−18\]

darkknight:
