Question

if the zeros of the quadratic polynomial representing the curve of Dish are - 5 and - 6 then the polynomial is:

a) x2 - 11x + 30 b) x2 - 11x - 30 c) x2 + 11x - 30 d) x2 + 11x + 30

Answer 1

Answer:

Answer D

Step-by-step explanation:

-5+(-6) = -11

-5×-6 =30

$\alpha + \beta = - \binom{b}{a} \\ \alpha \times \beta = \binom{c}{a}$
