Best ResponseYou've already chosen the best response.2Well the idea is to isolate y right? What would be your first step?

Best ResponseYou've already chosen the best response.2You have a cube root. How would you get rid of that?

Dido525

Best ResponseYou've already chosen the best response.2For instance, if you have a square root you have to square to get rid of the square root.

Best ResponseYou've already chosen the best response.2@francescazares2012 : You there?

francescazares2012

Best ResponseYou've already chosen the best response.1So I would cube both sides?

Best ResponseYou've already chosen the best response.1Is my answer 2?

francescazares2012

Best ResponseYou've already chosen the best response.1It didn't work. :/

Best ResponseYou've already chosen the best response.1√(x+10)=x+10

Best ResponseYou've already chosen the best response.2Okay, square both sides again :) .

francescazares2012

Best ResponseYou've already chosen the best response.1okay so now i have x+10=(x+10)^2

Dido525

Best ResponseYou've already chosen the best response.2Can you expand the (x+10)^2 ?

francescazares2012

Best ResponseYou've already chosen the best response.1okay I am a bit confused

francescazares2012

Best ResponseYou've already chosen the best response.1what I am supposed to do

Best ResponseYou've already chosen the best response.2Okay so we have: dw:1355462917095:dw

francescazares2012

Best ResponseYou've already chosen the best response.1okay I sort of see where this is going

Best ResponseYou've already chosen the best response.2You realize we have to foil this correct?

Best ResponseYou've already chosen the best response.2Algebra isn't that bad once you get the hang of it :) .

Best ResponseYou've already chosen the best response.1I am working on this problem right now and I got 3 but it says it's wrong. √(6a2)=16

francescazares2012
 2 years ago
Best ResponseYou've already chosen the best response.1not 16 I meant 4

francescazares2012
 2 years ago
Best ResponseYou've already chosen the best response.1so √(6a2)=4

Dido525

Best ResponseYou've already chosen the best response.2So square both sides :) .

Dido525
 2 years ago
Best ResponseYou've already chosen the best response.2Keep the negative inside the brackets when you square, so it would be like (4)^2 .

francescazares2012
 2 years ago
Best ResponseYou've already chosen the best response.1but wouldn't that be 16?

Dido525
 2 years ago
Best ResponseYou've already chosen the best response.2A genral rule is when you square both sides and the negative it attached to a number, You put the negative in brackets and them square it.

Dido525
 2 years ago
Best ResponseYou've already chosen the best response.2Because when you square you are basically going 4 * 4 which his 16 ( negative * negative is +) .

francescazares2012

Best ResponseYou've already chosen the best response.1Okay. Well I got the final answer to be 3. But it says that that is wrong. Why is that?

Dido525

Best ResponseYou've already chosen the best response.2So when you square both sides, what did you get?

Dido525
 2 years ago
Best ResponseYou've already chosen the best response.2It's strange, that's absolutely correct.

francescazares2012

Best ResponseYou've already chosen the best response.1That's what I thought. It's online hw. And it tells you when it's right or wrong.

Best ResponseYou've already chosen the best response.1nevermind it was does not exist

francescazares2012

Best ResponseYou've already chosen the best response.1probably because it was a 4

Best ResponseYou've already chosen the best response.2It depends on the sign of the square root.

Dido525

Best ResponseYou've already chosen the best response.2If it's a POSITIVE square root then yes, no solutions exist.

Dido525

Best ResponseYou've already chosen the best response.2But if it's √(6a2) then it's 3.

Dido525

Best ResponseYou've already chosen the best response.2Because when you take the square root of a function it's always in the form of ±√ f(x) . We need to know the proper sign.

Best ResponseYou've already chosen the best response.2We have: dw:1355464812127:dw

francescazares2012

Best ResponseYou've already chosen the best response.1so what do i do now?

Dido525

Best ResponseYou've already chosen the best response.2After squaring both sides?

Dido525

Best ResponseYou've already chosen the best response.2Get all the y's on one side.

francescazares2012
 2 years ago
Best ResponseYou've already chosen the best response.1I think I am having trouble squaring them.

francescazares2012

Best ResponseYou've already chosen the best response.1oh so I foil

Dido525

Best ResponseYou've already chosen the best response.2You should get the same answer no matter what you use.

francescazares2012

Best ResponseYou've already chosen the best response.1I am moving the y's

Best ResponseYou've already chosen the best response.1I think I am doing this wrong
