Find All Possible Rational Solutions

Use the Rational Root Theorem to determine the list of possible rational roots.

• A

• B

• C

• D

Which of the following is NOT a possible rational zero for p(x). 

• A

• B

• C

• D

Which of the following is NOT a possible rational root. 

• A

• B

• C

• D

Find all zeros.

• x= 3,1,1/3

• x= -3, -1, -1/3

• x = -3, 1, 1/3

• x = 3, -1, -1/3

Solve and check for extraneous solutions

• x=5

• x= -5

• No Solution

• n=-2

• {n= -2,12}

• No solution

• {n= 2,12}

Solve and check for extraneous solutions

• k = 20

• k = -20

• No Solution

• k = 3

• k=6

• k=-2

• k=-6

• k=4

• There is no solution because the solution x = 6 is extraneous
• x = 6
• x = 7
• x = 5

• r= -5

• r=2

• r=-2

• no solution
