Question

what is the value of determinant ?​

Answer 1

Hloo mates here's the answer ➡️❣️⬅️
In linear algebra, the determinant is a value that can be computed from the elements of a square matrix and encodes certain properties of the linear transformation described by the matrix. The determinant of a matrix A is denoted det(A), det A, or |A|. Geometrically, it can be viewed as the volume scaling factor of the linear transformation described by the matrix. This is also the signed volume of the n-dimensional parallelopiped spanned by the column or row vectors of the matrix. The determinant is positive or negative according to whether the linear mapping preserves or reverses the orientation of n-space.

Answer 2

Answer:

Determinant D= b^2-4ac

If D is 0 the quadratic equation has real and equal roots.

If Dis greater than 0 it has two distinct roots.

If D is -ve it has no roots.

These are applicable for quadratic equation where

b=constant number of second term

a=constant number of first term and

c= constant number of 3rd term
