$$-6 = -6 $$
$$9-15 = 4-10 $$
adding $\frac{25}{4}$ to both sides:
$$9-15+ \Big(\frac{25}{4} \Big) = 4-10+ \Big(\frac{25}{4} \Big) $$
(This is just like : $a^2 – 2ab + b^2 = (a-b)^2$.)
Here $a = 3$, $b=\frac{5}{2}$ for L.H.S., and $a =2$, $b=\frac{5}{2}$ for R.H.S.
So it can be expressed as follows:
$$ \Big(3-\frac{5}{2} \Big)^2 = \Big(2-\frac{5}{2}\Big)^2 $$
Taking positive square root on both sides:
$$ 3 - \frac{5}{2} = 2 - \frac{5}{2} $$
$$ 3 = 2 $$
but not clear. Can anybody help me?
Thanks in advance !!!
