Question

7xpower2 -25n -12 factorise it ​

Answer 1

Solution:

Given,

= 7x² - 25x - 12

By splitting the middle term, we get,

= 7x² - 28x + 3x - 12

Taking 7x and 3 as common, we get,

= 7x(x - 4) + 3(x - 4)

Taking (x - 4) as common, we get,

= (7x + 3)(x - 4) which is our required answer.

Answer:

• (7x + 3)(x - 4)
