None of them because the given term does not have an equality sign and therefore it is not an equation.
2.
There are no candidates below, so none of them. There are an infinite number of solutions to the equation, and from here, we can't see which ones are on your list of choices.
There are none. For this equation, there is nonreal answer, as the graph of the quadratic does not pass below the x-axis

Since the highest power of 'x' in the equation is '1', there's one solution.

Without an equality sign the given expression can't be considered to be an equation but if it equals 0 then using the quadratic equation formula will give its solutions.
Infinitely many

There are infinitely many solutions to the equation since it simplifies to 13 = 13, which is always true.
The discriminant is 1-4*2*(-1) = 1+8 = 9. This is greater than 0 so there are 2 real solutions.
5x2-136 = 24 5x2 = 24+136 5x2 = 160 x2 = 32 x = the square root of 32
Without an equality sign the given terms can't be considered to be an equation and so therefore no solutions are possible.
