Question:
While solving quadratic equations, how to split the middle term
Answer:
Let us take an example.
Example: Factorize x2 - 7x + 12
Now split the middle term in such a way that its sum is 7 and product is 12
So, x2 - (3 + 4)x + 12
=> x2 - 3x - 4x + 12
=> x(x - 3) - 4(x - 3)
=> (x - 3)*(x - 4)
In this way, we split the middle term.
