If x = −5 and x = 2 are roots, what is the sum of the roots?

Answer and explanation

Correct answer: −3

The governing operation is addition of the two given roots. The roots are −5 and 2, so their sum is (−5) + 2 = −3. Therefore option A is correct. The sign must be handled carefully: adding a positive number to a negative number means subtracting magnitudes, and the number with the larger absolute value determines the sign. Since |−5| is greater than |2|, the result is negative. Option B would result from reversing the sign or treating −5 as positive. Options C and D incorrectly add or subtract the magnitudes without applying the correct signed-number rule. The product of the roots would be −10, but that is not what the question asks.
