Let's assume
'a' , 'b' are zeros
so, we will find total zeros from graph
We can curve touches x-axis
Let's assume it touches at x=b
so, there would be two zeros at x=b
it also crosses origin
so, another zero is at x=0
it crosses x-axis one more time
Let's assume that zeros at x=a
so, we have got four zeros
x=a,0,b,b
now, we can set up function
we can also write as

Answer:
Total cost of topps card = $104.5
Step-by-step explanation:
Given:
Cost of each topps card = $5.50
Cost of each fleer card = $3.90
Total number of cards = 46
Total cost = $209.80
Find:
Total cost of topps card
Computation:
Assume;
Number of topps card = T
Number of fleer card = F
So,
T + F = 46.......eq1
and
Total cost of topps card = 5.50T
Total cost of fleer card = 3.90F
So,
5.50T + 3.90F = 209.80.....eq2
eq1 x 3.90
3.90T + 3.90F = 179.4.......eq3
eq2 - eq3
1.6T = 30.4
T = 19
Number of topps card = 19
Total cost of topps card = 5.50(19)
Total cost of topps card = $104.5
There needs to be 26. the 26th term will be 66
= -15 Multiply both sides by -3 to cancel out the fraction
x = 45
