The given function presents a local minimum in the coordinates (0,-1).
<h3>Factoring</h3>In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
For solving this question, the given equation should be rewritten from the factoring.
. Then, you have 3 equations.
From the Zero Factor Principle, you can write
Equation 1
(x+1)²=0
x+1=0
x= -1
Equation 2
x-1=0
x=1
Equation 3
x²-x+1=0
From these points it is possible to plot a graph and you can see that the local minimum presents the coordinates (0,-1).

Answer:
The parabolic equation does not intersect the linear equation.
Explanation:
Given equation's:
- y = x² − 5x + 9
- y = -2x
To solve , use substitution method by inserting 2nd equation into 1st
when substituted y = -2x
collect terms
simplify
Find discriminant:
As the discriminant is negative, it tell us that they both does not intersect each other.
