b.
(4m² - 9) / (3 + 2m)
= (2m - 3)(2m + 3) / (3 + 2m)
= 2m - 3

c.
(1 - m²) / m² + m - 2
= (1 - m)(1 + m) / (m + 2)(m - 1)
= -(m - 1)(1 + m) / (m + 2)(m - 1)
= -(1 + m) / (m + 2)
= -m - 1 / m + 2

d.
x² - 5x + 6 / 2x² + x - 10
= (x - 2)(x - 3) / (2x + 5)(x - 2)
= (x - 3) / (2x + 5)

e.
3x² + 10xy - 8y² / 6x² - 13xy + 6y²
= (3x - 2y)(x + 4y) / (2x - 3y)(3x - 2y)
= (x + 4y) / (2x - 3y)
