The polynomial function
If a function has a, b and c as its zeros, the function is:
So, we have:
Open the inner brackets
Expand the difference of two squares
Expand
The pie must stay for 60 - x more minutes must the pie bake
<h3>For how many more minutes must the pie bake?</h3>
Let the amount of time spent in the oven be x
So, we have
Total amount of time = 60 minutes
This means that
Remaining time + Amount of time spent = 60
This gives
Remaining time + x = 60
Evaluate
Remaining time = 60 - x
Hence, the pie must stay for 60 - x more minutes must the pie bake

Add dress and shoes together:
30 + 25 = 55
1/5 off means the total after discount would be 4/5 ( 1 - 1/5 = 4/5)
Multiply total price by 4/5:
55 x 4/5 = (55 x4)/5 = 220/5 = 44
Total after discount is 44
Now add shipping:
44 + 8 = 52
Total paid = £52
