Question
Check the equation is quadratic equation: $x^2+3 x+1=(x-2)^2$
✓
Answer
We have $x^2+3 x+1=(x-2)^2$
$\Rightarrow x^2+3 x+1=x^2-4 x+4$
$\Rightarrow 7 x-3=0$
It is not of the form $a x^2+b x+c=0, a \neq 0$
$\therefore$ the given equation is not a quadratic equation.
$\Rightarrow x^2+3 x+1=x^2-4 x+4$
$\Rightarrow 7 x-3=0$
It is not of the form $a x^2+b x+c=0, a \neq 0$
$\therefore$ the given equation is not a quadratic equation.
