Let A = [ a b c d ] over ℝ . Prove that if a d − b c = 0 , then A does not have an inverse.

To determine

To prove: Let A=[abcd]  over ℝ and ad−bc=0, then A does not have an inverse.

Explanation

Given information:

A=[abcd]  over ℝ and ad−bc=0.

Formula used:

Definition: Matrix multiplication

The product of m×n matrix A over ℝ and n×p matrix B over ℝ is m×p matrix C=AB, where the element cij in row i and column j of AB is found by using the elements in row i of A, and the elements in column j of B in the following manner:

                                                                              column j of B        column j of Crow  i  of A[⋮⋮⋮⋮ai1ai2ai3⋯ain⋮⋮⋮⋮]⋅[⋯b1j⋯⋯b2j⋯⋯b3j⋯⋮⋯bnj⋯]=[⋮<
