There was a type-o on 1) so I changed ) to 0 because that made the most logical sense to me.
solve each equation
1) 6x^3-13x^2-5x=0

x=0 or 2x-5=0 or 3x+1=0
x=0 or 2x=5 or 3x=-1
x=0 or x=5/2 or x=-1/3
:
2) 5(3a-1)^2+3=-16(3a-1)

Let 3a-1=p

5p+1=0 or p+3=0
5p=-1 or p=-3
p=-1/5 or p=-3
Let p=3a-1
3a-1=-1/5 or 3a-1=-3
3a=1-1/5 or 3a=1-3
3a=4/5 or 3a=-2
(1/3)(3a)=(1/3)(4/5) or 3a/3=-2/3
a=4/15 or a=-2/3
Happy Calculating!!!
