Advanced Math practice question

Answer: 0

The solutions are x = 5 and x = −5. Their sum is 5 + (−5) = 0.

Common wrong answers

If you answered 5

5 is one solution alone.

If you answered 10

10 adds 5 and 5, missing the sign of the second solution (x + 5 = 0 gives x = −5).

If you answered -25

−25 is the PRODUCT of the solutions, not their sum.
