  1. Answer:

    YES,IT IS A QUADRATIC EQUATION.

    Step-by-step explanation:

    since,ax^2+bx+c=0

    therefore,

    x+2=x^2-5

    =>(x^2)-5-x-2=0

    =>(x^2)-x-7=0

    so,in this equation,a=1,b=-1 and c=-7

    It is not of the form ax

    +bx+c=0

    Therefore,the given equation is not a quadratic equation.
