Find which of the following equations are quadratic:

$x_{2}+5x−5=(x−3)_{2}$

$x_{2}+5x−5=(x−3)_{2}$

Solution: $x_{2}+5x−5=(x−3)_{2}$

$⇒x_{2}+5x−5=x_{2}−6x+9$

$⇒11x−14=0;$

which is not of the general form $ax_{2}+bx+c=0$

And it's a linear equation.

Thus, the given equation is not a quadratic equation.

$⇒x_{2}+5x−5=x_{2}−6x+9$

$⇒11x−14=0;$

which is not of the general form $ax_{2}+bx+c=0$

And it's a linear equation.

Thus, the given equation is not a quadratic equation.
