Hey.....
(1) is a quadratic equation
(x+1)^2=2(x-3)
x^2+1+2x=2x-6
x^2+2x-2x-6+1=0
x^2-5=0
In this equation the highest power of x is 2 so it is a Quadratic equation
(2) is not a quadratic equation...
(x-2)(x+1)=(x-1)(x+1)
x^2+x-2x-2=x^2+x-x-1
x^2-x^2+x-2x-x+x-2+1=0
-x-1=0
In this equation it's maximum power is not 2 so this is not a Quadratic equation...
Hope this will help u...
