Explanation:
Let the equation be
a
⋅
x
2
+
b
⋅
x
+
c
. To factorize multiplication of a and c i.e. ac so that sum of factors, if ac is positive (and difference if ac is negative) is equal to b. Now split b into these two components and factorization will be easy.
Answer:
(-1 , 2) Not part of the solution
Step-by-step explanation:
from the graph:
(0 , 0) in the red part ⇒ it's a solution
(-1 , -2) in the red part ⇒ it's a solution
(1 , 2) in the red part ⇒ it's a solution
(-1 , 2) in the red part ⇒ it's Not a solution
