Domain - Reasoning with Equations and Inequalities
Cluster - Understand solving equations as a process of reasoning and explain the reasoning.
[AII.A-REI.A.2] - Solve simple rational and radical equations in one variable, and give examples showing how extraneous solutions may arise.
- Variable
A quantity that can change or that may take on different values. Refers to the letter or symbol representing such a quantity in an expression, equation, inequality, or matrix.
[AI.N-RN.A.2] -
Rewrite expressions involving radicals and rational exponents using the properties of exponents.
[AI.A-REI.A.1] -
Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify or refute a solution method.
[AI.F-BF.B.4.a] -
Solve an equation of the form f(x) = c for a linear function f that has an inverse and write an expression for the inverse.
