Question

Factorise 7a²(2x+3y)-8a²b(2x+3y)

Answer 1

Answer:

a²(7-8b)(2x+3y)

Step-by-step explanation:

7a²(2x+3y)-8a²b(2x+3y)

(7a²-8a²b)(2x+3y)

a²(7-8b)(2x+3y)

Answer 2

Answer:

The Correct Answer is (2x + 3y) a² [ 7 - 8b ]

Step-by-step explanation:

7a²(2x+3y) - 8a²b(2x+3y)

Taking (2x + 3y) common,

= (2x+3y) [ 7a² - 8a²b ]

Taking a² common,

= (2x + 3y) a² [ 7 - 8b ]
