Question 188893: 1b. 8xy / (24x /4)

1d. (3a - 6 / 6a +12) X (3a2 - 12 / a2 - 5a +6)

1c. (x - 7 / 3x2 - 8x +4) / (3x - 24 / 6x2 - 21)

1e. (4x - 6 / 4x + 8) X (6x + 12 / 4x2 - 9)

1f. (a2 - 9a + 14 / 3a - 6) / [(a - 7) (a + 7) / a2 + 4a + 21]

2a. (2x / 3) - (5x / 6) - 3 = (1/2x) - 5

2b. (4m / m-2) - (13 / 3m -6) = (1/5)

2c. (4 / x - 1) = (5 / x2 - x)

2d. (a / x2 - 4) = (2 / a +2)

2e. (x +1 / x2 - 9) = (1 / 3x + 9)

2f. (3x + 2 / 2x - 3 ) = (3x - 2 / 2x - 5)

2h. (4m / m - 2) - (13 / 3m - 6) = (1/3)

2i. (w +1 / w - 3) - (2w - 1 / w2 - 9)

Solve by factorization

3d. 5x2 - 40x = 0

3e. 36x2 - 81 = 0

3f. 4x2 - 16 =0

3h. x2 + 2x = 0

3i. 5x2 - 40x = 0

3j. x2 + x = 0
