Question

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.

ax+b+c=d

Use a constant in place of each variable a, b, c, and d. You can use positive and negative constants in your equation.

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.

Sorry mate i cannot help you at the moment! @agent0smith @Wolfboy @rational @elementwielder @satellite73 @FlvsGirl

Answer 5

k when can u

Answer 6

Thats a hard question XD

Answer 7

k

Answer 8

k

Answer 9

do u know anyone who can

Answer 10

Post a screenshot, because any equation of the form ax+b+c=d where a, b, c, and d are all real number constants, always has only one real solution.

Answer 11

screen shot of what

Answer 12

What do you think...? The question.

Answer 13

i copy and pasted it

Answer 33

can u plz help me plz do it and label ill be back on in a couple hours plz i really need this

Answer 34

@agent0smith

Answer 35

\[ax+b+c=d\] has no radical in it
my guess is it is
\[\sqrt{ax+b}+c=d\]

Answer 36

you could try
\[\sqrt{x+8}+2=5\] which has one nice solution \[\sqrt{x+8}+2=5\\
\sqrt{x+8}=3\\
x+8=9\\
x=1\]

Answer 37

for one that has no solution you could try the same thing only make it \[\sqrt{x+8}+2=-1\]

Answer 38

what is for what part

Answer 39

the second one has no solution
try it
you will also get \(x=1\) but \(1\) is not a solution to the original equation

Answer 40

look at this its the picture of what i need

yah

Answer 47

oh xD havent finished tht yet lol

Answer 48

i have 1 and 3 only need 2

Answer 49

i can help u with the first question...

Answer 50

k

Answer 51

Inser numbers for the a,b,c,d,e
ax√x+c+d=e
ax√x+c+d=e
Like this
2x√x+1+4=2 (For Extaneous Solution)
2x√x+1+2=4 (For Non-Extraneous Solution)

Answer 52

???

Answer 53

Any Questions?

Answer 54

there no e

Answer 55

?

Answer 56

u put x+c+d=e but no e its suppose to equal d

Answer 57

well excuse me for trying to help...

Answer 58

i not being mean just letting u know

Answer 59

all u gotta do is take out tht +1 on each my mistake sry

Answer 60

why is one Extraneous Solution and other is not

Answer 73

yes?

Answer 74

can u help me with

Answer 75

do you have two radical equations?

Answer 76

no

Answer 77

they give you a model of \[a \sqrt{x+b}+c=d\]
which is a to the square root of x+b then +c which should =d

Answer 78

they also say to use a constant of a,b,c,and d
they should be positive and negative numbers in your equation

Answer 79

ok i have no idea on how to do it i need alot of help

Answer 80

give me one sec while i figure it out, then ill explain

Answer 81

ok

Answer 82

ok... a radical equation has a square root in the equation...its considered to have an extraneous solution if the final answer does not actually work in the original equation

Answer 83

that tis not the answer though

Answer 84

can u make it for me its worth 100 points and i dont get it and if u do ill fan u and give u help with whatever u need i just dont get this lesson plz do it and label part 1 2 3 plz and thx
