Answer:

A. -11 is the other root

Answer:

A = -11

Step-by-step explanation:·

1. Your equation is : 1x^2+ 9x + −22 = 0

2. use quadratic formula with : a = 1 b = 9 c = -22

3. x =  -b ± √b2−4ac /2a

   x=  -(9) ±√(9)2−4(1)(−22) /2(1)

   x=  −9 ± √169 /2

therefore the answer is x = 2 or x = -11
