(a2 + 5a + 6)/(a - 2) = (a + 2)*(a 3)/(a - 2) which cannot be simplified further.
It can, however be written as (a2 - 2a + 7a - 14 + 20)/(a - 2)
which is (a + 7) + 20/(a - 2)
It simplifies to 5a+4 !

The square root of 25a squared is 5a. The square root of 16 is 4.So the answer is (5a+4)(5a-4)
This is not a difficult factorisation, as it is merely a normal factorisation with "a" stuck on the end of each number. 25a(2) - 20ab + 4b(2) (2b-5a)(2b-5a) This is: 2bx2b=4b(2) 2bx-5a=-10ab (twice) -5ax-5a=25a

2a + 11a - 5a = 8a
2a+5
a2 + -5a2 - a2 - a = a2 - 5a2 - a2 - a = a2 - 6a2 - a = -5a2 - a
