Question

A=[ matrix a&b\\ c^ prime &d matrix ] FIND F ^ - 1

Answer 1

Answer:

Solution:

A = B is impossible because A and B are of different sizes: A is 2 \times 2 whereas B is 2 \times 3. Similarly, B = C is impossible. But A = C is possible provided that corresponding entries are equal:

\left[ \begin{array}{cc} a & b \\ c & d \end{array} \right] = \left[ \begin{array}{rr} 1 & 0 \\ -1 & 2 \end{array} \right]

means a = 1, b = 0, c = -1, and d = 2.
