Objectives:

 Guidelines for Solving Radical Equations • Isolate the radical on one side of the equation. • Raise both sides of the equation the appropriate power to eliminate the radical . • Solve the resulting equation • Check solutions

Note: It is very important to check your solutions after solving a radical equation
because raising both sides of an equation to a power sometimes does not produce
an equivalent equation .

Examples: check: Therefore, the solution set is {4} Check: The solution set is {18}

An equation o quadratic form is one that can be written as by making
an appropriate substitution .

Examples:  then the equation becomes because we have  let , then the equation becomes because , we have  let , then the equation becomes Check:  therefore 4 is a solution , now because , we have  let ,then the equation becomes  Because ,we have Prev Next
