Question

sreeja says 2(x-1)^2=4x^2-2x+1 is a quadratic equation do you agree with her. give reasons​

Answer 1

Step-by-step explanation:

2 (x-1)^2=4x^2-2x+1

=> 2 (x^2 +1-2x) = 4x^2 -2x +1

=> 2x^2 +2 -4x = 4x^2 -2x+1

=> 2 -4x +2x -1 = 4x^2 -2x^2

=> -2x +1 = 2x^2

=> 0 = 2x^2 +2x -1

or 2x^2 +2x -1 = 0...

Yes, we agree with her bcz. the degree of the =n is 2 i.e it is a quadratic equation...
