An n x n matrix is a rectangular array of numbers or variables arranged in rows and columns. The size of the matrix is determined by the number of rows (n) and the number of columns (n).
Two rows in a matrix are considered identical if they have the exact same entries in the same order. This means that the values in each position of the row are equal.
A matrix with two identical rows has infinitely many solutions because there are multiple ways to express the same set of solutions. This is due to the fact that the two identical rows provide redundant information, allowing for different values in the remaining rows to still result in the same final solution.
No, a matrix with two identical rows cannot have a unique solution. This is because the two identical rows provide redundant information, resulting in an infinite number of solutions.
The number of solutions for a matrix with two identical rows can be determined by looking at the number of independent rows in the matrix. If there are two or more independent rows, there will be infinitely many solutions. If there is only one independent row, there will be a unique solution.
