Solve Square Roots Extraneous

This equation has...

• two positive solutions

• one positive solution and one negative extraneous solution

• one positive solution and one negative solution

• two negative solutions

Solve for x:
(x + 2)^1/2 - 5 = -2

• 1

• 5

• 7

• 9

• x = -2
• x = 22
• x = 1
• x = 2

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

Question 10

• -9/2

• 4/3

• 2

• ½

Find the value of x: √(x - 2) = 3

• 11

• 4

• 5

• 6

• n = 5 and -6

• n = -6

• n = 5

• No Solution

What is the solution to this square root function?

• z=11

• z=10

• z=7

• no solution

• Square both sides

• Divide both sides by 3

• Add 2 to both sides

• Subtract 2 from both sides
