Question

9x-x²-20 spilting the middle term​

Answer 1

$\huge\bigstar\blue{Answer}$

Here we go

Given :-

• A quadratic polynomial = 9x - x² - 20

__________________________

We have to split the middle term

-x² + 9x - 20

= = > x² - 9x + 20

= = > x² - 5x - 4x + 20

= = > x( x - 5 ) - 4( x - 5 )

= = > ( x - 4 ) ( x - 5 )
