which of the following shows the Foil method of multiplying (2x-4) and (3x +3)?
[tex] \large{\sf{Solution}}[/tex]
[tex] \large{\tt{(2x - 4) \: (3x + 3)}}[/tex]
[tex] \tt{ = (2x) \: (3x) + \: (2x) \: (3) + \: ( - 4) \: (3x) + \: ( - 4) \: (3)}[/tex]
[tex] \tt{= 6 {x}^{2} + 6x - 12x - 12}[/tex]
[tex] \bold{\tt{= 6{x}^{2} - 6x - 12}}[/tex]
[tex] \large{\sf{Answer}}[/tex]
[tex] \sf{(2x - 4) \: (3x + 3)} \: = \: \boxed{\large{\sf{6 {x}^{2} - 6x - 12}}}[/tex]
