Please help me to answer the question below in detail. I really don't understand it. Thank you so much, and have a great day!

1 . :1 Consider M(2:,y) + N(:r:, y) * 3E : 0. (a) Suppose we can nd functions p and 2 so that (p. o z)(:i:1 y) is an integrating factor that transforms the given equation into an exact equation. What must be true about M and N '? (h) Continuing from part (a)1 suppose we can nd functions it and 2: so that (poz)(m, y) is an integrating factor that transforms the given equation into an exact equation. Construct a differential equation with respect to ,u to solve for pt. (C) Using the 0131?. with respect to [I in part (b) , given \"(20) : #0: when does a unique solution estt? (d) Suppose z : 2:2 + 3;\". Find ,1: from part (b), if possible. (e) Construct an example of an equation that can be solved using the integrating factor in part (d) and then solve this equation
