Question

Check whether the following are quadratic equations:
(x − 1)2 = (x + 1)2

Answer 1

Step-by-step explanation:

given,

( x - 1)² = (. x + 1)²

=> x² + 1 -2x = x² + 1 + 2x

x² + 1 will be cancelled from both sides.

=> -2x = 2x

=> -2x - 2x = 0

=> -4x = 0

it is not in the form of ax² + bx + c

so, it is not a quadratic equation.
