Which equation is quadratic in form?
4(x – 2)2 + 3x – 2 + 1 = 0
8x5 + 4x3 + 1 = 0
10x8 + 7x4 + 1 = 0
9x16 + 6x4 + 1 = 0

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
