Kindly solve this question pls..​

Answer 1

Factorization of 25a² - 35a + 12

Length * Breadth = 25a² - 35a + 12

Split the middle terms :-

[25 * 12 = 300

300 = 2 * 2 * 5 * 5 * 3

300 = 20 * 15

So, - 35a = 20a - 15a]

= 25a² - 20a - 15a + 12

= 5a(5a - 4) - 3(5a - 3)

= (5a - 3)(5a - 4)

So, Length = (5a - 3) and breadth = (5a - 4)
