விளக்கம்:

(i) $\frac{1}{x^{2}}+\frac{1}{y^{2}}+\frac{2}{x y}

$=\frac{1}{x^{2}}+\frac{2}{x y}+\frac{1}{y^{2}}

$=\frac{1}{x^{2}}+\frac{1}{x y}+\frac{1}{x y}+\frac{1}{y^{2}}

$=\frac{1}{x}\left[\frac{1}{x}+\frac{1}{y}\right]+\frac{1}{y}\left[\frac{1}{x}+\frac{1}{y}\right]

$=\left[\frac{1}{x}+\frac{1}{y}\right]\left[\frac{1}{x}+\frac{1}{y}\right]

$=\left[\frac{1}{x}+\frac{1}{y}\right]^{2}

$\frac{1}{x^{2}}+\frac{1}{y^{2}}+\frac{2}{x y} என்ற சமன்பாட்டின் காரணி \left[\frac{1}{x}+\frac{1}{y}\right]^{2} ஆகும்.

(ii) 8 m^{3}-2 m^{2} n-15 m n^{2}

m\left[8 m^{2}-3 m n-15 n^{2}\right]

=m\left(8 m^{2}-12 m n+10 m n-15 n^{2}\right)

=m[4 m[2 m-3 n]+5 n[2 m-3 n]]

=m[2 m-3 n][4 m+5 n]

=m[2 m-3 n][4 m+5 n]

8 m^{3}-2 m^{2} n-15 m n^{2} என்ற சமன்பாட்டின் காரணி m[2 m-3 n][4 m+5 n] ஆகும்.
