Step-by-step explanation:
we know that
A quadratic equation is a polynomial of second degree
so
Verify each case
case 1) we have
therefore
This is a quadratic equation, because is a polynomial of second degree
case 2) we have
This is a polynomial of fifth grade
therefore
Is not a quadratic equation
case 3) we have
This is a polynomial of eighth grade
therefore
Is not a quadratic equation
case 4) we have
This is a polynomial of sixteenth grade
therefore
Is not a quadratic equation
