Answer» Thank you guys
Eguation power has 2
If a equation is of the form ax^2+bx+c=0 and a is not 0 ,a,b,c are real numbers then the equation is a quadratic equation.
If the eqation has highest power 2
Quadratic equation is the equation which have degree of 2 &In the form of 2 ax. +bx + c =0
If the given equation has the highest degree 2 then it is a quadratic equation.
If the highest power of variable ( degree ) in an eqiation is 2 then it is a quadratic equation.
