Part a: factor 2x2y2 + 6xy2 + 18x2y2. show your work. part b: factor x2 + 10x + 25. show your work. part c: factor x2 − 36. show your work.

A.

B.

C.

Step-by-step explanation:

Part A. The expression consists of three terms: The first and the last terms are like terms, we can add them:

Now,

So,

Part B. The expression is a square of so

Part C. Use the difference of squares formula:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
