Hello, ceasar_19134!

As written, I see no way to solve the equation . . .

Could the problem be:
. . Find the product of all real solutions of: $16x^2+x+4\:=\:32 + x^2+2x$

Then we have: . $15x^2 - x - 28\:=\:0\quad\Rightarrow\quad x^2 - \frac{1}{15}x - \frac{28}{15}\:=\:0$

Then the product of the roots is: $-\frac{28}{15}$
