Explanation:
We have to multiply each of the terms inside the bracket by - 4
That is
(9-4n)(-4)=color(red)(-4)(9-4n)(9−4n)(−4)=−4(9−4n) and distributing the bracket.
color(red)(-4)(9-4n)=(color(red)(-4)xx9)+(color(red)(-4)xx-4n)−4(9−4n)=(−4×9)+(−4×−4n)
=-36+16n=16n-36larr" in standard form"=−36+16n=16n−36← in standard form
