For every species of seed, there is an optimal soil temperature for germination, and at that temperature, the maximum number of seeds will germinate and in less time than at any other temperature. You can sow onion seeds at 32ÂºF and get 90% germination.
Algebraic Expression â a number, variable, or combination of the two connected by some mathematical operation like addition, subtraction, multiplication, division, exponents and/or roots.
So algebraic numbers can be irrational, for example â2. This number is algebraic because it is the solution of the equation x2 â 2 = 0, whose coefficients are all rational (in fact, integer): 1 and -2. Algebraic numbers were one of the main points of interest in Ramanujanâs work.
