why x2 . y2 = (x-y) (x+y) and xy . y2 cannot be (x-y) (y+y)
If by x2 . y2 you mean ##x^2\cdot y^2##, then it is not equal to ##(x-y)(x+y)##.Atqiya said:why x2 . y2 = (x-y) (x+y) and xy . y2 cannot be (x-y) (y+y)
The purpose of operations in scientific research is to carry out a specific set of procedures or actions in order to collect data, test hypotheses, and draw conclusions. These operations can range from simple tasks such as measuring and recording data to complex experiments involving multiple variables.
Some common types of operations used in scientific research include observation, experimentation, data collection, data analysis, and statistical analysis. These operations can be used in various combinations depending on the research question and methodology.
To ensure accuracy and precision in operations, it is important to follow standardized protocols and procedures, use calibrated instruments, and repeat experiments multiple times. It is also crucial to minimize any external factors that may affect the results.
Potential sources of error in operations can include human error, equipment malfunction, environmental factors, and sample contamination. It is important to identify and minimize these sources of error in order to obtain reliable and valid results.
To improve operations for better results, it is important to carefully plan and design experiments, use appropriate and validated methods, and carefully analyze and interpret data. Seeking feedback from peers and experts can also help improve operations and results.
