We can split the middle term of a4 + 5a2 + 6 as :
a2 and 4a2
7a2 and -2a2
3a2 and 2a2
6a2 and –a2
a4 + 5 a2 + 6
We need to look for two numbers whose product is 6 and sum is 5.So they are 3 and 2, hence the answer.
While factorizing x2 - 5x + 6, the middle term can be split as the sum of ____________.
Middle term split
x2+2√2x-6
Splitting the middle term, what do we get as the factors of x2 - 2√3x + 3?
