Draw the graph of these eqns. And explain also how?
X2+2x+1=0
-X2-2x-1=0
Both the mentioned equations are same and the solution is x = -1 .
multiplying equation 2 with -1 we will get the first equation.
the equation 1 is in the form of
(a+b)2 = a2 + b2 + 2ab
we will get ,
(x+1) = 0.
hence x = -1.
the graph of the equation will be a straight line passing through the x axis at -1.
if you want i will paste the graph also.
please approve the answer if helpful .
