Question

how would you solve this

Answer 1

1. subtract 5 from both sides. 2. square both sides. 3. bring everything to one side. 4. attempt to factor directly or use quadratic formula. x^2-11x+24 is what you should attempt to factor. Which may be imaginary, have you covered this?

Answer 2

yes
i have

Answer 3

so would x be 3

Answer 4

Sorry, this isn't actually imaginary, but x is not 3 either. What method did you use?

Answer 5

i am just sloving radical equations

but since x isnt 3
would it be 8

Answer 6

yes, one of them is 8 and the other is 3. So (x-8)(x-3)=0. Quadratic formula spits it out right away for you.

Answer 7

and also, sorry about that you were right before haha.. doing this in my head and yeah

Answer 8

wait
x=3
x=8

Answer 9

am i right

Answer 10

yup

Answer 11

I think with these kinds of problems they assume the principal value of the square root (just the positive value).

Answer 12

ok great

Answer 13

do u want to help me on this one

Answer 14

@phi

Answer 15

what is the difference between a radical equation and an equation simply containing a radical

i need an example, but i would like to make one up my self

Answer 16

A radical equation is one where the variable is found under a square root. An equation containing a radical is just where a number is found under a square root within the equation. Try to make one up?

Answer 17

ok

Answer 18

boings answer sounds good

Answer 19

would this do it
