Methods of factorising polynomials
There are various methods of factorising a polynomial. They are, 1. Factorisation by dividing the expression by the HCF of the terms of the given expression. 2. Factorisation by grouping the terms of the expression. 3. Factorisation using..
Steps for factorisation using remainder theorem
By trial and error method, find the factor of the constant for which the given expression becomes equal to zero. Divide the expression by the factor that is determined in step 1. Factorise the quotient. If the quotient is a trinomial, factorise it further. I..
Multiple shootlet production
Large number of genetic replicas of rare hybrid or sterile valuable plant can be produced asexually by culturing shoottips. Since propagation is vegetative, the problems of heterogeneity, pollination, divergent inheritance, chromosomal and gene transformations are completely avoided in such m..
Abbreviations in powers of 10 (used in SI units)
>Full names of the units do not begin with capital letter E.g., newton and not Newton. The symbols of units, named after a scientists, have initial capital letter. E.g., J for joule, K for Kelvin. Symbols do not have plural form. E.g., 5 kg (not 5 kgs), 25 m (not 25 metres). A unit symbol is repres..

Crop improvement by deliberate attempt to cross two parents of desirable characters to incorporate such characters in next generations is called breeding. The entire process of pollination, fertilization and regeneration is kept under control and selected parents are allowed to reproduce ..
Introduction
When calculating sides or angles of right angled triangles, it is easiest to use the appropriate trigonometric relation. Finding the value of trigonometric ratios from the tables is learnt easily. Nowadays of course calculators are able to give accurate values for any degree of tan, sin o..

Commercial Utility of Hybridization
. Use of commercial hybrids invariably involves inbred plants as parents -which means parental purity is maintained by not allowing pollen from other varieties to fertilize. The success of hybrid crop and its heterosis is much dependent on purity of parents. As against this, hybridization..
Point of intersection of two lines
Then (x 1 , y 1 ) lies on both (i) and (ii). Solving for x 1 and y 1 by the method of cross multiplication, we obtain ..
