The image you've provided shows a determinant (or matrix) proof involving variables like , , and . Here's a step-by-step breakdown of what appears in the image:
-
The matrix is given as a 3x3 determinant:
\begin{array}{ccc} bc - a^2 & ca - b^2 & ab - c^2 \\ ab - c^2 & bc - a^2 & ca - b^2 \\ ca - b^2 & ab - c^2 & bc - a^2 \end{array} \right|$$ -
Below the determinant, the text indicates the goal of the proof or calculation, which is to show that this determinant equals the expression .
This type of determinant is often used in proofs related to symmetric polynomials or cyclic sums, and the structure suggests that it's a part of a proof showing that the determinant of this matrix can be simplified into the square of a symmetric polynomial involving , , and .
