= 0
We can write 64 as
+
= 0
using the identity ( )
we get,
=
= ....................(1)
solving the quadratic equation ,
=0
solutions of this quadratic equation can be obtained by
let use y for factors
<u /> ..................(2)
from the equation 1 we have,
which gives solution
and from equation 2 we got
so the real solutions for the equation are -
