What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
How do you solve an algeraba problem?
There are lots of different types of problems in algebra; you have to learn each type separately. For example, how to add similar expressions; how to multiply expressions; how to factor polynomials; how to solve equations; etc.
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 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.
What is the difference between algebra equations and expressions?
expressions don't have an equal sign and equations do
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
How are equations and expression similar?
Equations are made from expressions.
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.
Compare and contrast equations and inequalities?
Inequalities and equations are both the same because they are both mathematical expression and they both use the same steps EXCEPT for the end. Inequalities and equations are both different because equations have an equal sign, the answer is not an interval, and the answer is a specific answer. Not a range. While inequalities don't have an equal sign, its answer is an interval, and it's answer is in a range.
Equations that contain rational expressions?
a rational function.
What are the similarities between equations and expressions?
Both have a value
What is the same about expressions and equations?
They both have numbers and symbols
