Answer:
The correct answer is A..
Step-by-step explanation:
From the Invertible Matrix Theorem (IMT) we have a set of equivalent conditions to determine if a square matrix is invertible or not. In particular, it says that a square matrix of dimension tex]n\times n[/tex] is invertible if and only if, its columns span the vector space tex]R^n[/tex].
In the particular case of this exercise we have a matrix of dimension tex]5\times 5[/tex]. So, by the Invertible Matrix Theorem its columns must span the vector space tex]R^5[/tex]. Now, according to the statement of the exercise this condition does not hold. Hence, the given matrix cannot be invertible.

is 
.
Step-by-step explanation:
Let be a second-order polynomial (quadratic function) is standard form and equalized to zero:
Its roots can be determined by the Quadratic Formula in terms of its polynomial coefficients, which states that:
Given that 
, 
and 
, the roots of the polynomial are, respectively:
The solution set of the quadratic function is .
