Answer 1

b)

`\frac{3 {a}^(2) - 9a}{ {a}^(2) - 9} = (3a(a - 3))/((a + 3)(a - 3)) = (3a)/(a + 3)`

c)

`\frac{ {y}^(2) - 3yz -4 {z}^(2) }{3 {y}^(2) - 12yz } = ((y + z)(y - 4z))/(3y(y - 4z)) = (y + z)/(3y)`

d)

`\frac{ {d}^(2) + 4d + 4}{ {d}^(2) + 2d} = ((d + 2)(d + 2))/(d(d + 2)) = (d + 2)/(d)`

e)

`\frac{5f - 15}{3 {f}^(2) - 13f + 12} = (5(f - 3))/((3f - 4)(f - 3)) = (5)/(3f - 4)`

I hope I helped you^_^
