Question

Tristan says that solutions to radical equations are extraneous. Hadley says that solutions to radical equations are non-extraneous. Find an equation where Tristan is correct and a second equation where Hadley is correct. Using complete sentences, explain each step when solving to justify your examples.

Answer 1

Tristan:
√x-2=−3

x−2=9

x=11

Check:
√11-2=−3

9√=−3

3≠−3,extraneous

Answer 2

Hadley:
√x-2=3

x−2=9

x=11

Check:
√11-2=3

9√=3

3=3,non−extraneous

Answer 3

does that make sense

Answer 10

Sorryy I fell asleep @israa88 But the question is Debbie and trisha are looking at the equation ' The square root of 4x-6 = the square root of x ' Debbie says that the solution is extraneous. Trisha says the solution is non-extraneous. Is debbie correct? Is Trisha correct? Are they both correct? Justify your response by solving this equation, explaining each step with complete sentences.
