Question

How to do middle term splitting method easily without wasting time in examination??

Answer 1

hey mate ur ans
its very easy like
a^2-3a-54
in this example we find that we have to split
3a in such a way that it on Adding or subtracting should be 3 and on multiply it should be 54 so let's find
9*6=54:9-6=3
so it is perfect now
a*2 +6a-9a +54
Take common
a(a-6)-9(a-6)
(a-9)(a-b)
