(a+b) (x+y)=a^2+b^2
Solve the problem
With step by step​

Answer 1

Answer:

Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, radiation, and physical properties of matter. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, chemical engineering and mechanical engineering, but also in other complex fields such as meteorology.

Answer 2

Answer:

(a-b)x+(a+b)y=a^2-2ab-b^2

(a+b) (x+y)=a^2+b^2
