part 1. create two radical equations: one that has an extraneous solution, and one that does not have an extraneous solution. use the equation below as a model:
a√x+b+c=d
part 2. show your work in solving the equation. include the work to check your solution and show that your solution is extraneous.
part 3. explain why the first equation has an extraneous solution and the second does not.

part a)

for extraneous solution

1 ⋅ sqrt(x+2) + 3 = 0

for non extraneous solution

1⋅ sqrt(x+2)  + 3 = 6

part b) solve each equation

1⋅sqrt(x+2)+3=0

x+sqrt(x+2)=−3

square both sides

(sqrt(x+2))^ 2 = (−3)^2

x+2=9

x=9−2

x=7

'a number' means x

A. a number times 7 means x times 7 or 7x, yep
B. a number subtracted from 7 means 7-x, yep
C. sum of a number and 7 means add them so 7+x, yep
D. a number divided by 7 means x/7, this is the wrong one

D is answer
