Question

sum of the numbers is -9 and product is 14 . write the quadratic polinomial and it's factors
​

Answer 1

Step-by-step explanation:

A+B = -9

A+B = -b/a ( sum of alpha and beta)

AB = c/a. ( product of alpha and beta )

c/a = 14

-b/a = -9

polynomial is x^2 + 9x + 14

factors are (x+2) (x+ 7)
