Step-by-step explanation:
[tex] \space[/tex]
We have,
[tex] \longrightarrow \sf{4(x + y) (3a – b) + 6(x + y) (2b – 3a)}[/tex]
[tex] \space[/tex]
[tex] \: \: \sf{ = x + y) [4(3a – b) + 6(2b – 3a)]}[/tex]
[tex] \space[/tex]
[tex]\: \: \sf{ = ( x + y) [12a – 4b + 12b – 18a]}[/tex]
[tex] \space[/tex]
[tex] \: \: \sf{ = (x + y) [-6a + 8b]}[/tex]
[tex] \space[/tex]
[tex] \: \: \sf{ = (x + y) 2(-3a + 4b)}[/tex]
[tex] \space[/tex]
[tex] \: \: \sf{ = (x + y) 2(4b – 3a)}[/tex]
[tex] \space[/tex]
