14. Yes
15. Yes
Step-by-step explanation:
We can determine the degree of the equation by looking the highest value of the unknown. The highest value must be equal to 1
In number 12, the highest value of the unknown represented by the variable x was 2.
Also, in number 13, 3x(x-1) gives the output 3x² - 3x making the highest degree of the unknown equal to 2.
