Question
Check the equation is quadratic equation or not: $x^2- 2x = (-2)(3 - x)$
✓
Answer
$ x^2-2 x=(-2)(3-x) $
$ \Rightarrow x^2-2 x=-6+2 x $
$ \Rightarrow x^2-2 x-2 x+6=0 $
$ \Rightarrow x^2-4 x+6=0$
Here, degree of equation is $2$.
Therefore, it is a Quadratic Equation.
$ \Rightarrow x^2-2 x=-6+2 x $
$ \Rightarrow x^2-2 x-2 x+6=0 $
$ \Rightarrow x^2-4 x+6=0$
Here, degree of equation is $2$.
Therefore, it is a Quadratic Equation.
