( 12x – 3 )( 2x – 2 )

= 24x² – 24x – 6x + 6

= 24x² + ( -24x – 6x) + 6

= 24x² – 30x + 6

1) ( 12X – 3 ) ( 2X – 2 )

→ 12X × 2X – 12X × 2 – 3 × 2X – 3 × ( –2 )

→ 24X² – 12X × 2 – 3 × 2X – 3 ( –2 )

→ 24X² – 24X – 3 × 2X – 3 × ( –2 )

→ 24X² – 24X – 6X – 3 × ( –2 )

→ 24X² – 24X – 6X + 6

→ 24X² – 30X + 6 ✓
