A) $( 5 x - 17 y ) ( 9 a + b )$
B) $45 a x - 153 a y - 5 b x + 34 b y$
C) $5 x - 17 y ( 9 a + b )$
D) $( 5 x - 17 y ) 9 a + b$
E) $45 a x - 153 a y + 5 b x - 17 b y$

Notice that both terms share a common factor of $9a+b$. So, we can factor out this common factor to get $5x(9a+b)-17y(9a+b)=(5x-17y)(9a+b)$ as desired.

Factor Completely 5x(9a+b)−17y(9a+b)5 x ( 9 a + b ) - 17 y ( 9 a + b )5x(9a+b)−17y(9a+b)

Factor Completely $5 x ( 9 a + b ) - 17 y ( 9 a + b )$
