Class 10 Math All topics Quadratic Equations

Check whether the following are Quadratic equations

$x_{2}+3x+1=(x−2)_{2}$

$x_{2}+3x+1=(x−2)_{2}$

Solution:

$x_{2}+3x+1=(x−2)_{2}$

$x_{2}+3x+1=x_{2}−4x+4$

$⇒x_{2}+3x+1−x_{2}+4x−4=0$

$⇒7x−3=0$ has its highest power $1$

Hence it is not a quadratic equation.
