1. Move all terms to one side
2x^2+3x+1=0
2. Find the numbers for a, b and c
a=2
b=3
c=1
3. Put the numbers into the formula
3^2-4(2)(1)
4. Simplify
9-4*2*1
9-8
1
The key thing to note is that percentage means that number over 100. Thus 55% can be written as 55/100. This converts to the decimal 0.55. If we then multiply this by 80, we get 44.
