Frequently Asked Questions

What is a matrix determinant?

The determinant is a scalar value computed from a square matrix. For a 2×2 matrix [[a,b],[c,d]], det = ad - bc. It indicates if the matrix is invertible.

When is a matrix not invertible?

A matrix is not invertible (singular) when its determinant equals zero. This means the matrix rows are linearly dependent and the system has no unique solution.

What is the quadratic formula?

The quadratic formula is x = (-b ± √(b²-4ac)) / (2a). It finds the roots of any equation in the form ax² + bx + c = 0, where a ≠ 0.

What does the discriminant tell you?

If the discriminant (b²-4ac) is positive, there are two distinct real roots. If zero, there is one repeated root. If negative, the roots are complex numbers.
