Answer 2

விளக்கம்:

(i) $m^{2}+\frac{1}{m^{2}}-23$

$m^{2}+\left(\frac{1}{m}\right)^{2}+2 \cdot m \cdot \frac{1}{m}-2-23$

$\left(m+\frac{1}{m}\right)^{2}-25$

$\left(m+\frac{1}{m}\right)^{2} -5^2$

$\left(m+\frac{1}{m}-5\right)\left(m+\frac{1}{m}+5\right)$

(ii) $6-216 x^{2}$

$6\left[1-6^{2} x^{2}\right]$

$=6\left[1^{2}-(6 x)^{2}\right]$     [ ∴ $(a^2-b^2)=(a+b)(a-b)$]

$\begin{aligned}&=6[(1+6 x)(1-6 x)]\\&=6(1+6 x)(1-6 x)\end{aligned}$
