Add your answer:
How are math expressions and math equations the same?
They are the same except equations use the equal sign =
How can you solve problems involving equivalent expressions?
In the same way that you would solve equations because equivalent expressions are in effect equations
What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
Expressions that have the same value?
If both equations can be simplified to the same value, they are equal.
How are equations and expression similar?
Equations are made from expressions.
Compare and contrast equations and inequalities?
Equations assert the equality of 2 expressions and Inequalities are comparisons of expressions
Do equations and expressions have addition?
They can but don't have to.
Do algebraic expressions have equals signs?
no algebraic expressions do not have equal signs but equations do.
What are the solutions to -x squared plus 2x plus 4 and x-2?
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
How are word problems with equations different from word problems with expressions?
It may be possible to solve equations. Expressions cannot be solved until they are converted, with additional information, into equations or inequalities which may have solutions.
Equations that contain rational expressions?
a rational function.
What are the similarities between equations and expressions?
Both have a value
What is equivalent ratio's equation?
Equations are said to be equivalent if they have the same solution. This definition also holds true in rational equations or equations involving rational expressions. For instance, the equations 2x = 14 and x - 3 = 4 are equivalent. Why? It's because they have the same solution, that is x = 7.
What is a math statement where two expressions have the same value?
They are called: Identical equations or IdentitiesSee: http://www.tutorvista.com/search/value-algebraic-expressions-33 - -7 = ss = -26
What is an advantage to using equations?
When given two names (variable expressions) for the same quantity, you can use algebra to solve the equation.
What is an advantage to using what equations?
When given two names (variable expressions) for the same quantity, you can use algebra to solve the equation.
Arithmetic rules for evaluating expressions and equations?
formula expression
Do expressions have an equal sign in math?
No they do not, equations have equal signs.
What is the meaning of equations?
"Equations" is the plural form of "equation". An "equation" is a mathematical statement that two expressions are equal.
Is the foil method used for factoring quadratic equations?
Yes FOIL method can be used with quadratic expressions and equations
How are algebraic expressions and equations alike?
Algebraic expressions are the written relations of or between variables. For example, x2, 1/x, and x + y + z are all algebraic expressions. Algebraic equations are simply algebraic expressions that equate to something. For example, x2 = 4, 1/x = y, and x + y + z = 42 are all algebraic equations. In general, one differentiates algebraic expressions from exponential, trigonometric, hyperbolic, and logarithmic expressions by requiring algebraic expressions to be confined to polynomial expressions. I've added a link regarding polynomials below.
What is a statement that two numberical or variable expressions are equal?
equivalent equations
How are math expressions and math equations different?
Math equations have an equals sign such as: 7+5=12 or 9x6=47+7 Math expressions do not have a equals sign such as: 43-27 or 8x40
Do the equations 2x 4y9 and -4x-8y4 have a solution?
The given expressions can't be considered to be equations because there are no equality signs.
Is addition and subtraction examples of equations?
Addition and subtraction are mathematical processes. They can be used in equations, which are statements that the values of two mathematical expressions are equal, but they are not equations by themselves.
