Answer 2

Step-by-step explanation:

Given Sum of the zeros of the polynomial p (x) = x square - kx + 9 is 7. Find the value of k.

• General form of quadratic equation will be ax^2 + bx + c = 0
• Now the given quadratic equation is x^2 – kx + 9
• So here a = 1, b = - k and c = 9
• Now sum of roots is given by – b/a
•                      So sum of roots is 7
•       So 7 = - (-k) / 1
•         Or k = 7
