The Fahrenheit scale was based on freezing water when salt and ice were mixed together. This happened at what is now 0F. The scale upper number was set to the temperature of the human body at about 100F. When the scale was refined then water froze at 32F and boiled at 212F. 212 minus 32 equals 180. Since the C scale is based on water's freezing and boiling points, or 0C and 100C, the relationship is 100/180, or 5/9. The -32 simply zeros out the two scales. Cirric

C = 5/9( F-32) = 5/9(59-32) = 15C For most people that is on the cool side - comfortable level is 68-72F in normal humidity conditions
Start by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5. This is how you convert Fahrenheit to Celsius or use the equation C = (F - 32) × 5/9
Start by taking the number in Fahrenheit and subtracting 32. Then divide the number by 9, and then multiply it by 5. This is how you convert Fahrenheit to Celsius or use the equation C = (F - 32) × 5/9In this case, the answer is about -9.44 degrees Celsius.

Whenever there are polynomials of the form aX2+bX+c=0 then this type of equation is know as a quadratic equation. to solve these we usually break b into two parts such that there product is equal to a*c and I hope you know how to factor polynomials.
