15ab ( a^2 - 7a + 10 ) / 3b ( a -2 )
= 15ab ( a ^2 - 5a - 2a + 10 ) / 3b ( a - 2 )
= 15ab [ a ( a - 5 ) -2 ( a - 5 ) ] / 3b ( a - 2 )
= 15ab ( a - 2 ) ( a - 5 ) / 3b ( a - 2)
= 5a ( a - 5 )
= 15ab ( a ^2 - 5a - 2a + 10 ) / 3b ( a - 2 )
= 15ab [ a ( a - 5 ) -2 ( a - 5 ) ] / 3b ( a - 2 )
= 15ab ( a - 2 ) ( a - 5 ) / 3b ( a - 2)
= 5a ( a - 5 )
