Here are the polynomial models that describe the median annual income for men, M, and for women, W, who have completed x years of education:

• M=177x²+ 288x + 7,075
• W=255x²- 2,956x + 24,336

1. Find a mathematical model for M - W.
2. What is the difference in the median annual income between men and women with 14 years of education?

**Be very clear and detailed

** And use basic algebra and not Triganometry or calculus
