Question 2786

Here's an example:
4x² + 3x + 10  =  x(4x + 3 + 10/x)


You simply divide everything by x:
4x² : x = 4x  (...as x ∙ 4 x = 4x²)
3x : x = 3  (...as x ∙ 3 = 3x)
10 : x = 10/x (...as x ∙ 10/x = 10)


x(4x + 3 + 10/x)  →  If you multiply everything in ( ) by x you will get 4x² + 3x + 10  
4x² + 3x + 10  →  If you divide everything in ( ) by ex you will get x(4x + 3 + 10/x)
