216/10 = 21.6 = 22
22 x 3.99 = 87.78
22 x 4.99 = 109.78
216 x 1.00 = $216
87.78+109.78 = 197.56
216 - 197.56 = 18.43

eimsori [14]
when you use all prime, non-one numbers for b and c, it cannot be factored most of the time


example
1x^2+7x+5
a=1
b=7
c=5
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-7+/- \sqrt{7^2-4(1)(5)} }{2(1)}
x=\frac{-7+/- \sqrt{49-20} }{2}
x=\frac{-7+/- \sqrt{29} }{2}
x=\frac{-7+ \sqrt{29} }{2} or \frac{-7- \sqrt{29} }{2}
