Question

some equation of algebraic expressions.​

Answer 1

An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms. They are also termed algebraic equations.

Examples

3x + 4y – 7, 4x – 10, etc.

These expressions are represented with the help of unknown variables, constants and coefficients. The combination of these three (as terms) is said to be an expression. It is to be noted that, unlike the algebraic equation, an algebraic expression has no sides or equal to sign. Some of its examples include

3x + 2y – 5

x – 20

2x2 − 3xy + 5

Answer 2

Answer:

mark me as brainliest

Step-by-step explanation:

x + y + z)2 = x2 + y2 + z2 + 2xy +2yz + 2xz. (x + y – z)2 = x2 + y2 + z2 + 2xy – 2yz – 2xz. (x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz. (x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz.
