A quadratic equation is written in the form
ax^(2) + bx + c = 0

Looking at the second, third, and fourth options, we see that the highest powers are greater than two, which automatically disqualifies them from being quadratics (since the highest power in a quadratic is 2).

This makes the first option the correct choice since the expansion of the equation gives
2x^(2) + 28x + 61
