Question

check whether the following equation is quadratic equation.
1) x^2-4x=x^2-2x ​

Answer 1

Answer:

no this is linear equation as x^2 on both sides cancels each other

Answer 2

${x}^{2} - 4x = {x}^{2} - 2x \\ { x }^{2} - {x}^{2} = - 2x + 4x \\ \\ \\ hence \: thi s\: eqn \: is \: not \: a \: quad \: eqn$

as it is not in the form of

${ax}^{2} + bx + c = 0$
