Question
Check the equation is quadratic equation or not: $(x + 1)^2= 2(x – 3)$
✓

Answer

The given equation is $(x+1)^2=2(x-3) \Longrightarrow x^2+2 x+1-2 x+6=0$
$\Longrightarrow x^2+7=0$
$\Longrightarrow x^2+0 \cdot x+7=0$
Which is of the form $a x^2+b x+c=0$
Hence, the given equation is a quadratic equation.
