Answer:
Answer:
+ 9x + 8 = 0
Step-by-step explanation:
First, we have to simplify this quadratic equation:
(x+2)^2 + 5(x+2) - 6 = 0
x^2 + 4x + 4 + 5x + 10 - 6 = 0
x^2 + 9x + 8 = 0
Given:
The matrix equation is:
To find:
The value of matrix C.
Solution:
Let . Then the given equation can be rewritten as
On substituting the values of the matrices, we get
Therefore, the correct option is C.
