it's already a perfect square.....

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: {9x}^{2} - 24x + 16 = {(3x)}^{2} - 2(3x)(4) + {4}^{2} \\ {9x}^{2} - 24x + 16 = {(3x - 4)}^{2}$

So, zero must be added to it.....

Hope it helps you.....

Answer 2

Answer:

6 should be added.

This will make the eq.

9x square - 24x + 16

Step-by-step explanation:

Simplification --

(3x)square + (4)square - (2 * 3x *4)

{using identity (a + b -2ab) = (a-b)whole square}

we get.

(3x - 4)whole square
