Quadratic equation is the polynomial equation in which the highest degree of its variable is two.The highest degree of the equation given in option 1 is four and thus it is a quadratic equation. Hence, option 1 is the correct option.
<h3>Quadratic Equation</h3>
Quadratic equation is the polynomial equation in which the highest degree of its variable is two.
Let's check all the given options one by one whether it is a quadratic equation or not.
Option 1-
simplify the above equation using the algebraic formula of the whole square, we get,
The highest degree of the equation given in option 1 is four and thus it is a quadratic equation.
Option 2-
The highest degree of the equation given in option 2 is four and thus it is not a quadratic equation. hence option 2 is incorrect.
Option 3-
The highest degree of the equation given in option 3 is six and thus it is not a quadratic equation. hence option 3 is incorrect.
option 4-
The highest degree of the equation given in option 4 is nine and thus it is not a quadratic equation. hence option 4 is incorrect
Hence, the highest degree of the equation given in option 1 is four and thus it is a quadratic equation. Hence, option 1 is the correct option.
