Solve for x; identify extraneous solutions (if any).

• x = 3; x = - 1 is extraneous

• x = - 1; x = 3 is extraneous

• x = 3; x = - 1

• no solution; x = 3 and x = - 1 are extraneous

What is a "Extraneous Solution"

• Roots that have more no solution

• Roots that have more than one solution. One of them works

• Roots that have more tha one solution. None of them work

• Roots that have more tha one solution. Both of them work

• x = -2
• x = 22
• x = 1
• x = 2
