Question

X+1\x=-2 Is it quadratic equation

Answer 1

No,
To be a quadratic eqn it should have a degree of 2 but,
x+1=-2(x)
x+1+2x=0
3x+1=0
here the degree is 1.
Therefore, it is not a quadratic eqn

Answer 2

Hey there

$\frac{ x + 1}{x} = - 2 \\ \\ x + 1 = - 2x \\ \\ 3x +1 = 0$
which isn't in the form of ax^2 +bx+x
hence it isn't a Quadratic equation

Hope it helps you ☺
