Q35 Factorise the following:
a) 3(a + b) (2x - y) + 7(a + b) (-5y + 6x)​

Answer 1

Step-by-step explanation:

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

taking (a+b) common

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

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

(a+b)(-29x+39y)

Answer 2

Answer:

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

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)
