product of two binomials with like terms fomula

What is the number of terms in the product (8 + 7 )(8 - 7 ) , after like terms have been combined? => 2 or 0 or 3 or 1..

When the coefficient of the highest power is 1. i.e., ax 2 bx c, when a = 1 and b and c are integers. When two binomials are multiplied the product is a trinomial. Thus (x + 4) (x + 5) = x 2 + 9x + 20 (1) (x - 4) (x - 5) = x 2 ..

Natural resources characteristically exhibit two features. They are: 1) Physical limitations 2) Limitations of regeneration / production. Natural physical resources like geophysical, hydro-geological, edaphic, atmospheric resources exhibit physical limitation..

An organism, in which number of complete chromosome sets is more than the diploid number is called polyploid. It is usual practice to express the chromosome number of an organism in diploid, symbolically represented by 2n. In all sexually propagated crops, such expression is of specific s..

x 2 - 2x - 48 = x 2 - 8x + 6x - 48 = x(x - 8) + 6(x - 8) = (x - 8) (x + 6) When the coefficient of the highest power is not unity. i.e., type ax 2 bx c, when and b and c are integers. Multiply (3x + 2) (x + 4) and consider the result ..

Introduction - The term 'natural resources' refers to all the natural things on our earth. It includes everything, that is naturally available and that is not creatable by any human activity. It specifically excludes the materials created by man. Human being and his anthropological histor..

. In maize, 130 composites and hybrids with high yield potentiality have been developed so far. Some early maturing hybrids with high yielding qualities are Vivek - 9, Pusa early hybrid Makka - 3, JH 3459, KHMH - 175, Kohinoor and Aravalli Mekka - 1. High protein hybrids like Shaktiman - ..

? One has not anticipated some of the impacts of industrial and technological advancement. When the industrial revolution started some 250 years ago, the world population was at 600 million - that seems like a lot of people but now the world population is now almost ten times at 6 billion..

Summary - Organic evolution refers to the slow and gradual process by which living organisms have changed from the simplest unicellular form to the most complex multi-cellular forms that are existing today. Organic evolution primarily involves modifications in the existing organisms and the inherit..

. to reduce the dependence on hydrocarbon fuels. A related aspect of management of these resources is the emissions they create in terms of pollution levels and green house gases. The choice of efficient technology or alternate fuel and technologies/products has a direct bearing..
