If the matrix is of 2 by 2 then we can find the determinant of the matrix.
Then (ad - bc ) gives you the determinant of the matrix.
For example,
= (2)(-2) - (1)(4)
= - 4 - 4
= -8
What is the intermediate step in the form (x + a)2 = b as a result of completing the square for the following equation? -3x2 – 1
