a) (5[tex]a^{2}[/tex] + 2a - 3b) - (3[tex]a^{2}[/tex] + 7a + 6b) =

5[tex]a^{2}[/tex] + 2a - 3b - 3[tex]a^{2}[/tex] - 7a - 6b

2[tex]a^{2}[/tex] - 5a - 9b

b) (2pq - 5p + 3q) - (6pq - 2q)

2pq - 5p + 3q - 6pq + 2q

- 4pq - 5p + 5q

c) (-[tex]x^{2}[/tex] + 3y) - (3y + 3[tex]x^{2}[/tex] - 2xy)

-[tex]x^{2}[/tex] + 3y - 3y - 3[tex]x^{2}[/tex] + 2xy

- 4[tex]x^{2}[/tex] + 2xy
