What is the simplified form of -3z^2(z+2)-4(z^2+1)

The ice rink sold 95 tickets for the afternoon

skating session, for a total of $828. General admission

tickets cost $10 each and youth tickets cost $8 each.

How many general admission tickets and how many

youth tickets were sold?

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

if you was gonna solve for a, a is a   < -12
