The answer to this is + 3x +4. You need to know what the standard form of a quadratic polynomial is. If you are not familiar with a quadratic polynomial, this is a polynomial of degree 2 or a quadratic. The highest degree term in this polynomial is the 2nd degree.


The normal formula for the quadratic polynomial is x1,2 = (-b ± √b² - 4ac) / 2a. Knowing this can be vital for you, especially if you would need to solve differential equations. Take note that the formula also requires a square root that you have to solve to get the right answer to your question. Take note that a quadratic function is not the same as a second-degree polynomial function.
