B Correct answer
Explanation

For x^2 + 7x + 10 = 0, the factors are (x+2)(x+5) = 0. The roots are -2 and -5. The statement claims the roots are 2 and -5, which is incorrect.

AI explanation

To find the zeroes of the polynomial x^2 + 7x + 10, factor the quadratic expression into (x + 5)(x + 2) = 0. Setting each factor to zero gives x = -5 and x = -2. Since -2 is not 2, the given statement is False.
