Examples of an algebraic expression
What are 3 algebraic expressions?
Algebraic Expression Formulas
- (a + b)2 = a2 + 2ab + b2
- (a – b)2 = a2 – 2ab + b2
- (a + b)(a – b) = a2 – b2
- (x + a)(x + b) = x2 + x(a + b) + ab.
- (a + b)3 = a3 + 3a2b + 3ab2 + b3
- (a – b)3 = a3 – 3a2b + 3ab2 – b3
- a3 + b3 = (a + b) (a2 – ab + b2)
What is algebraic expression give 2 examples?
An algebraic expression is a mathematical phrase where variables and constants are combined using the operational (+, -, × & ÷) symbols. An algebraic symbol lacks the equal (=) sign. For example, 10x + 63 and 5x – 3 are examples of algebraic expressions.

Examples of expression in a Sentence
He uses some very odd expressions. The expression “to make fun of” means “to ridicule.” Judging from her expression, I think the gift was a complete surprise. We saw his expression change from angry to sad.
How do you solve algebraic equations?
A General Rule for Solving Equations
- Simplify each side of the equation by removing parentheses and combining like terms.
- Use addition or subtraction to isolate the variable term on one side of the equation.
- Use multiplication or division to solve for the variable.
How do you know if it is an algebraic expression?
Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation. For example, 2x+4y−9 is an algebraic expression. Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
What is an algebraic equation explain with example for class 6?
Algebraic Equation
On the left side of the equation is the left-hand side(LHS) and the right side of the equation is the right-hand side(RHS). LHS and RHS are balanced by the same values. Example: x + 4 = 7, where x = 3.
How do you simplify algebraic expressions?
To simplify algebraic expressions, start by identifying the like terms, which are terms that have the same variables and exponents. Then, combine the like terms by adding them together to get the simplified expression.
How do you solve an algebraic expression word problem?
To solve an algebraic word problem:
- Define a variable.
- Write an equation using the variable.
- Solve the equation.
- If the variable is not the answer to the word problem, use the variable to calculate the answer.
