First, you have to combine all the like terms such as both the 2x’s and 16 and 12 which will give us 28+4x=396. Then you subtract 396 from 28 which is 368. You want the variable x to be alone so you divide 368 by 4 which gives you 92.

Step-by-step explanation:

(16 + 2x)(12 + 2x)

= 4x^{2} + 24x + 32x + 192 = 396

4x^{2}  + 56x - 204

this then becomes the answer of

4(x + 17) \times (x - 3)
