Seeing the connectors

How many connectors and terms in the following and group like terms:

1.      A = 8r -2r² – ½ πr²

2.      f(x) = 2x³ -9x² + Ax + B, A and B are constants.

3.      y = 2x³ – x² + 4x

4.      log(3x + 2) + 6 log2 = 2 + log (2x + 1)

5.      log (x – 8) + log (9/2) = 1 + log(x/4)

6.    2tan²z + 11sec z + 7 = 0

7.    4sin2 x = 6 – 9cos x

8.    3cos y + cot y = 0

9.    cos 2x = 2 cos x

10.cot x sin 2x = 1 + cos 2x

11.sin 3x = 3 sin x - 4 sin³ x

1.   2x² + 13x + 6 = 0

2.   3x² – 10x – 25 = 0

3.   x² – 7x + 12 = 0

4.   x² + 13x + 42 = 0

5.   6x² + x  - 35 = 0

P(x) = 2x³ +  3x² - ax + b
P(x) = x³ - x² +  ax +  b
