Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. There is no equality symbol in the equation and if one is inserted before the 31, the solutions do not work.
One way to make the question work is to rewrite the quadratic equation as
x2 - 10x + 31 = 0 which requires adding 3 characters (all in bold).
It is therefore impossible to be certain about the answer to your question. If that is the case, the radix is 13. Otherwise, please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared".

Using the quadratic equation formula: x = -5-/+ the square root of 7
What are the solution to the quadratic equation below 12x2 plus 4x-50?
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.
What is 9x2 equals 10x plus 2?
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
How many solutions does the equation 14x plus 2 equals 12x have?
That looks like a linear equation (no quadratic or higher terms), so you can expect it to have a single solution. However, actually solving the equation is not difficult; do it, to confirm this.
Is there a solution to the quadratic equation of 3x squared -10x equals -5?
Yes because rearranging it into the form of 3x2-10x+5 = 0 makes the discriminant of the quadratic equation greater than zero which means it will have two different solutions. Solving the equation by means of the quadratic formula gives x as being 2.721 or 0.613 both corrected to 3 decimal places.
If the discriminant of a quadratic equation equals zero what is true of the equation?
It has one real solution.
