Final answer:
The polynomial with a degree of 2, a leading coefficient of 12, a linear coefficient of -2, and a constant of 3 is 12x² - 2x + 3 = 0.
Step-by-step explanation:
The student is asking for a polynomial with specific coefficients and degree. To write down this polynomial, we need to arrange the terms with the given coefficients and constant into the standard form of a quadratic equation, which is ax² + bx + c = 0. Here, the leading coefficient a is 12, the linear coefficient b is -2, and the constant c is 3.
The resulting polynomial with the given conditions would be: 12x² - 2x + 3 = 0.
This quadratic polynomial has a degree of 2, satisfying the requirement. Remember that the degree of a polynomial is determined by the highest power of the variable x that appears in the equation.
