Question

Solve for b:

Answer 1

\[\LARGE 9a^2 b^2=3a^2\]

Answer 2

\[\huge 3\cancel{3a^2}b^2=\cancel{3a^2}\]

Answer 3

how many values of b?

Answer 4

How many values multiplied by themselves equal 1/3?

Answer 5

?

Answer 6

?

Answer 7

what do u mean?

Answer 8

I mean How many values multiplied by themselves equal 1/3?

Answer 9

$$b^2=\frac{1}{3}$$

Answer 10

you can also re-write as
b^2-a^2=0
(b-a)(b+a)=0
difference of two squares hence two answeres

Answer 11

\[b^2-\frac{1}{3}=0\]
\[(b-\sqrt{1/3})(b+\sqrt{1/3})=0\]

Answer 12

You can not cancel out "a" since we don't know if that'll be equal to 0 or not.

=> a^2 ( (3b)^2 -1) = 0

Answer 13

??

Answer 14

\[\LARGE 9a^2 b^2-3a^2=0\]
\[\LARGE 3a^2(3 b^2-1)=0\]
a=0 b=0
and other two real values
and a and b are those ellipse equation wale constant here..how can it be 0

Answer 15

So a is not 0, that means you can cancel it out

Answer 16

so b= +- sqrt(1/3)

Answer 17

how do we know a is not 0

Answer 18

SInce it denotes length of major axis of ellipse!

Answer 19

yeah so point ellipse :P
ellipse doesn't exist

Answer 20

its not wrong mathematically..

Answer 21

yep, mathematically its not, theoretically it is

Answer 22

okay :o
