how to solve middle term

Answer»

Assuming you asked this question for quadratic equation

For example consider :4x² + 17x + 4

Now rule to split middle term is think two numbers whose sum is 17 and product is 16.

So, observing gives the numbers are 1 and 16

4x² + 16x + x + 4

4x( x + 4) + 1 ( x + 4)

( 4x + 1) ( x + 4)
