Equivalent algebraic expressions are those expressions which on simplification give the same resulting expression. To represent equivalent expressions an equality = sign is used.
what is an equivalent expression?
Equivalent expressions are expressions that are the same, even though they may look a little different. If you plug in the same variable value into equivalent expressions, they will each give you the same value when you simplify.
what are coefficients?
In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. For example, if y is considered as a parameter in the above expression, the coefficient of x is −3y, and the constant coefficient is 1.5 + y.
what is an equivalent?
Equivalent Numbers Equivalent means equal in value, function, or meaning. In math, equivalent numbers are numbers that are written differently but represent the same amount.
What is a numerical expression?
Numerical Expression Definition. A numerical expression is a mathematical sentence involving only numbers and one or more operation symbols. Examples of operation symbols are the ones for addition, subtraction, multiplication, and division.
What are two ways to write equivalent algebraic expressions?
Other Answers 3(x + 3) and 3x + 9 are equivalent expressions, because the value of both the expressions remains same for any value of x. The expressions 6(x 2 + y + 2) and 6×2 + 6y + 12 are equivalent expressions and can also be written as 6(x2 + y + 2) = 6×2 + 6y + 12. You may also read,
What is the difference between equivalent expressions and equivalent equations?
equivalent expressions have the same value but are presented in a different format using the properties of numbers eg, ax + bx = (a + b)x are equivalent expressions. Strictly, they are not “equal”, hence we should use 3 parallel lines in the “equal” rather than 2 as shown here. Check the answer of
What is an example of an equivalent expression?
Examples of Equivalent Expressions 3x+2 and 3x + 6 are equivalent expressions, because the value of both the expressions remains same for any value of x. For instance, for x = 4, 3x+2 = 34+2 = 18 and. 3x + 6 = 3 x 4 + 6 = 18.
What is an expression in expanded form?
Expanded FormExpanded form refers to a base and an exponent written as repeated multiplication. ExponentExponents are used to describe the number of times that a term is multiplied by itself. ExpressionAn expression is a mathematical phrase containing variables, operations and/or numbers. Read:
How do you write an expression in math?
An example of a mathematical expression with a variable is 2x + 3. All variables must have a coefficient, a number that is multiplied by the variable. In the expression 2x + 3, the coefficient of x is the number 2, and it means 2 times x plus 3.
How can properties help to write equivalent algebraic expressions?
We use properties to simplify algebraic expressions. When we simplify an algebraic expression using properties, we can compare the original expression with the simplified expression to make sure they are equivalent. A simplified expression is always equivalent to the original.
What is equivalent addition?
The addition problem on the left side of the equals sign is equivalent to the addition problem on the right side. That means they both equal the same number. One number is missing. Type in the number that makes the problem on the left equal the same number as the problem on the right. “
What is the product of?
In mathematics, a product is the result of multiplying, or an expression that identifies factors to be multiplied. Thus, for instance, 15 is the product of 3 and 5 (the result of multiplication), and is the product of and. (indicating that the two factors should be multiplied together).
How do you simplify algebraic expressions?
Here are the basic steps to follow to simplify an algebraic expression: remove parentheses by multiplying factors. use exponent rules to remove parentheses in terms with exponents. combine like terms by adding coefficients. combine the constants.
