I need help with eight and nine you are to multiply the binominaals using the horizontal format

Answer:
8. [tex]15m^2-31m+10\\[/tex]
9. [tex]x^2y^2z^2+2xyz-3[/tex]
Step-by-step explanation:
[tex](a+b)(c+d)=ac+ad+bc+bd\\(3m-5)(5m-2)=3m*5m+3m(-2)-5*5m(-2)\\=3m*5m+3m(-2)-5*5m(-2)\\=15m^2-31m+10[/tex]
^#8^
[tex](xyz+3)(xyz-1)=xyzxyz+xyz(-1)+3xyz+3(-1)\\=xyzxyz+xyz(-1)+3xyz+3(-1)\\=x^2y^2z^2+2xyz-3[/tex]
^#9^
