Question

9x-x²-20 spilting the middle term​

Answer 1

$\huge\bigstar\blue{Answer}$

Here we go

Given :-

• A quadratic equation 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 )

__________________________

Answer 2

$: \implies\sf{ - {x}^{2} + 9x - 20} \\ : \implies\sf{ {x}^{2} - 5x - 4x - 20 } \\ : \implies\sf{ x(x - 5) - 4(x - 5)} \\ : \implies \sf \pink{( x - 4) \: ( x - 5)}$
