second degree polynomial

Second Degree Polynomials

Second degree polynomials are also known as quadratic polynomials. Their shape is known as a parabola. Long before the language of algebra was developed the ancient Greeks recognized the parabola as a conic section, and were also able to define it as the collection of all points equidistant from a point (focus) and a line (directrix).

What is a second degree polynomial? + Example –

A degree of a polynomial is the highest power of the unknown with nonzero coefficient, so the second degree polynomial is any function in form of: #P(x)=ax^2+bx+c# for any #a in RR-{0};b,c in RR#. Examples. #P_1(x)=2x^2-3x+7# – this is a second degree polynomial. #P_2(x)=3x+7# – this is not a second degree polynomial (there is no #x^2#)

Does hydrogen dissolve in water? – Quora

Partial pressure equals the concentration times the total pressure. Hydrogen has a very low solubility in water, based on its Henry’s constant. So it does dissolve, but the amount is very low when compared to nitrogen, oxygen or other gases.

How do hydrogen bonds affect solubility? + Example

The presence of hydrogen bonding between molecules of a substance indicates that the molecules are polar. This means the molecules will be soluble in a polar solvent such as water. Some examples of polar molecules which can hydrogen bond are ammonia (#NH_3#) and methanol (#CH_3OH#).



Solubilities given for those gases which react with water, namely ozone, nitrogen oxides, chlorine and its oxides, carbon dioxide, hydrogen sulfide, hydrogen selenide and sulfur dioxide, are re- corded as bulk solubilities; i.e., all chemical species of the gas and its reaction products with water are included.

Why is ammonia soluble in water? – Quora
