Describe and correct the error to solving the equation.


A There is an extraneous solution of x=−4x=−4, so the solution is x=5x=5.
b There is an extraneous solution of x=5x=5, so the solution is x=−4x=−4.cThe absolute value cannot be negative, so there is no solution.d The absolute value cannot be negative, so one solution must be extraneous.
