An expression which contains polynomials in both the numerator and denominator?
rational expression
Why can't the denominators of rational expressions be zero How can we find the domain of a rational function?
Rational expressions are fractions and are therefore undefined if the denominator is zero; the domain of a rational function is all real numbers except those that make the denominator of the related rational expression equal to 0. If a denominator contains variables, set it equal to zero and solve.
What is the difference between expression and equation?
The difference between these two is that an expression only contains variables, numbers, and mathematical symbols, and an equation contains two expression with an equal sign that separate them. For example, while an expression is "2x-1", an equation is "2x-1 = 5x."
How do you solve -7p-5-33?

How do you simplify an expression that contains a fraction bar?
If there is a common factor between the numerator and the denominator, you can eliminate it. Otherwise, there is usually not much to simplify.
What is a fraction that contains one or more fractions in the numerator the denominator or both?
It is a compound fraction.
What is a fraction that contains one or more fractions in the numerator and the denominator or both?
That's a complex fraction.
What fraction that contains one or more fractions in the numerator the denominator or both?
That's a complex fraction.
What would be the answer to -16m 71?
-16m + 71 = 0Subtract 71 from both sides of the equation.-16m = -71Divide the whole equation by -16.m = 71/16The negative in the numerator and the negative in the denominator cancel each other leaving the final product positive.
What are the usage of polynomials in real life?
The usage of polynomials in real life include mathematical models for the stock market, roller coaster designs, rocket trajectories, and in engineering for high and machine designs. A polynomial is a mathematical expression that contains exponents, variables, and constants.
What expression is undefined when y equals 4?
There are infintely many posibilities: Any expression that contains (y-4) or a multiple of it in the denominator. Also, the following trigonometric functions: An expression that contains arcsin(x/y) where abs(x) < 4 Similarly arccos Corresponding conditions for arccosec and arcsec.
What is a type of expression that contains a variable or variables?
An algebraic expression is a type of expression that contains a variable or variables.
What is an expression that contains at least one variable.?
An algebraic expression is a type of expression that contains a variable or variables.
What is the part of a fraction that tells how many units the fraction contains?
It is the denominator
