Let the number be 'x'

Since, the product of number and 4 less than twice that number is 336.

$x \times [(2 \times x) -4] = 336$

$x[2x -4] = 336$

$2x^2 -4x- 336=0$

$x^2-2x-168=0$

Now, we will split the middle term, we get

$x^2-14x+12x-168=0$

$x(x-14)+12(x-14)=0$

$(x-14)(x+12)=0$

So, $(x-14)=0 or (x+12)=0$

So, x = 14 or x = -12

Therefore, the negative number is '-12'.
