What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
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.
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.
Does an equation have an equal sign?
yes. equations have an equals signs and expressions don't
How are equations and expressions different?
An expession has NO equal sign, a equation are to amounts that are equal
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.
What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
How are equations and expression similar?
Equations are made from expressions.
What are equivalent expressions?
Two or more expressions (equations are examples) that are equal to or equivalent to each other; for example: (X+2)(X+4) = X^2+6X+8.
Non-examples of a formula?
Algebraic expressions can't be considered to be formulae or equations because they don't contain equality signs.
Do equations and expressions have addition?
They can but don't have to.
How can you solve problems involving equivalent expressions?
In the same way that you would solve equations because equivalent expressions are in effect equations
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
