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:
[tex](16 + 2x)(12 + 2x) [/tex]
[tex] = 4x^{2} + 24x + 32x + 192 = 396[/tex]
[tex]4x^{2} + 56x - 204[/tex]
this then becomes the answer of
[tex]4(x + 17) \times (x - 3)[/tex]
