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:

A quadratic equation is in the form

Hence, we can say that the degree of the quadratic equation is 2.

Now, we will use this concept to determine which of the given option is quadratic in form.

The first function has a degree of 2. Other function has some other degrees.

Therefore, the quadratic equation should be
