At Wyzant, connect with algebra tutors and math tutors nearby. It can provide solutions for simple and compound inequalities. Explain the usefulness of factoring by guiding the student through problem 2. It also shows its work so users can better understand how it reached the solution.
It also graphs the entered equation. Instructional Implications Explain what it means for expressions to be equivalent i. How is factoring related to the Distributive Property? Provide instruction on the Distributive Property and be very clear in describing what the property means.
Review the terms variable, constant, and coefficient. Sign up for free to access more Algebra resources like. Examples of Student Work at this Level The student combines like terms either correctly or incorrectly but does not factor the expression: To check an answer to a system of equations containing x and y, enter the two equations separated by a semicolon, followed by the sign and an ordered pair containing your x-value and y-value.
Examples of Student Work at this Level The student uses the fewest number of terms and correctly factors each expression.
Attempts to rewrite the expression as an equation and solve for x. The student does not understand what it means to write an equivalent expression. Be sure the student understands that the Distributive Property applies to subtractions as well since any subtraction can be rewritten as an addition.
To prove two expressions are equivalent, properties and theorems must be used. Evaluating Expressions Algebra Calculator can evaluate expressions that contain the variable x.
Examples of Student Work at this Level The student rewrites: Can you explain the Distributive Property? Exponents may not be placed on numbers, brackets, or parentheses. It provides some tutorial information and the formulas used to solve combinations and permutations.
Here is an example evaluating the expression xy at the point 3,4: Instructional Implications Challenge the student to factor each expression in a variety of other ways.
They are not next to each other in the expression. Simply input your data and it provides the result.
Questions Eliciting Thinking What does it mean for expressions to be equivalent? Is there more than one way to apply the Distributive Property?
Checking Answers For Solving Equations Just as Algebra Calculator can be used to evaluate expressions, Algebra Calculator can also be used to check answers for solving equations containing x. It includes examples with step-by-step explanations of how the equations are solved.
Substitutes a value for x and attempts to evaluate the expression. Be sure the student understands that a demonstration that two expressions are equivalent for a variety of values does not constitute a proof that they are equivalent. Instructional Implications Provide direct feedback to the student regarding his or her error and allow the student to correct it.
What does the word distribute mean? Then guide the student to use the information that the ages sum to 51 to write an equation. To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the sign and an ordered pair containing your x-value and y-value.
Guide the student to check factorizations by expanding and comparing to the original expression. Says the sum of and 9 is positive three. Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.
Multiplies terms together and attempts to evaluate the expression. Divides one of the terms, 16, by 4. Ask the student to identify examples of variables, constants, and coefficients in the expressions.Simplifying radical expressions; Simplifying radical expressions calculator.
