Question

prove that both the roots of the equation x minus A into x minus b + x minus b into x minus 3 plus x minus 3 into x minus 1 equal to zero real but they are equal only when a equals to B equals to C ​

Answer 1

Answer:

some cases, polymers form branching networks rather than single chains. Regardless of their shape, the molecules are very big. They are so big, in fact, that scientists classify them as macromolecules. Polymer chains can include hundreds of thousands of atoms — even millions. The longer a polymer chain, the heavier it will be. And, in general, longer polymers will give the materials made from them a higher melting and boiling temperature. Also, the longer a polymer chain, the higher its viscosity (or resistance to flow as a liquid). The reason: They have a greater surface area, which makes them want to stick to neighboring molecules.
