Question

factories : ) 3(a + b) (2x - y) + 7(a + b) (-5y + 6x) ​

Answer 1

Answer:

2 (a+b) (24x -19y)

Step-by-step explanation:

3(a + b) (2x - y) + 7(a + b) (-5y + 6x)

= (a + b) (3(2x - y) + 7 (-5y + 6x) )

= (a+b) (6x - 3y-35y + 42x)

= (a+b) (48x -38y)

= 2 (a+b) (24x -19y)

so

3(a + b) (2x - y) + 7(a + b) (-5y + 6x) = 2 (a+b) (24x -19y)
