Given the task definition, example input & output, solve the new input case.
Given a simple high-school level math question, you are required to solve it and provide the final answer. The final answer is always a single number. These questions can range from a variety of topics like simple arithmetic, solving equations, converting a quantity from one unit to another, finding remainders/GCD/LCM, finding probabilities etc. Each question has only one correct answer. This answer can be a positive or negative integer, a fraction or a decimal number. If the answer is a negative number use the hyphen (e.g. -42) symbol for the minus sign. For decimal numbers, do not add extra zeros after the decimal point. For fractional numbers, separate the numerator and denominator using a forward slash (e.g. 3/25).
Example: Let y = -74 - -79. Solve 0 = -y*q - 13 + 3 for q.
Output: -2
Solving the two equations, we find that the value of q is -2. The solution can be obtained by simply solving the equations one after another using substitution.

New input case for you: Let g = 3 - -7. Let f(h) = 9*h**2 + 14*h + 2. Let s be f(-4). Calculate the highest common factor of s and g.
Output:
10
