Lesson Plan
Solving radical equations (extraneous solutions)
Goals / Objectives
Solve a radical equation by isolating the radical, squaring, solving the resulting linear or quadratic equation, and checking every candidate in the original equation, rejecting any that are extraneous
Explain why squaring both sides of an equation can produce values the original equation excludes
Solve an equation containing a rational exponent by converting to radical form or raising to the reciprocal power
Decide, before solving, whether a given equation requires a verification step
Standards
"Make strategic use of algebraic structure, the properties of operations, and/or reasoning about equality to solve: • linear absolute value equations in one variable or simple rational and radical equations in one variable." "• including rewriting simple rational expressions, rewriting expressions with rational exponents in radical form, and factoring polynomials not included in the preceding bullet."
