# 63-66 Determinant Equations Solve for x . | 1 0 x x 2 1 0 x 0 1 | = 0

To determine

To solve:

The determinant equation |10xx210x01|=0 for the values of x.

Explanation

Approach:

The determinant is a value assigned to a square matrix.

The determinant of a n×n matrix A is denoted by det(A) and is given below.

det(A)=|A|=|a11a12a1na21a22a2nan1an2ann|=a11A11+a12A12++a1nA1n

Where, A1n is the nth cofactor corresponding to the element a1n.

Calculations:

Consider the determinant equation |10xx210x01|=0
