Question

X^-2 = (2+or-square root of 3)
Drawn out please

Answer 1

I showed you already. Please be patient and don't repost. Did you have questions about the solution I presented?

Answer 2

i need to see it worked out to get it

Answer 3

im new at this but is there a way to draw it out to see it?

Answer 4

\[x^{-2}=2 \pm \sqrt3\]\[\frac{1}{x^2}=2 \pm \sqrt3\]\[x^2=\frac1{2 \pm \sqrt3}\]\[x=\sqrt{\frac1{2 \pm \sqrt3}}\]

Answer 5

Just look at my solution one step at a time

Answer 6

If you are confused about a step, ask what was done or why

Answer 7

each line is a single step

Answer 8

\[\large x^{-2} = 2 \pm \sqrt{3}\]\[\large \implies \frac{1}{x^2} = 2\pm \sqrt{3}\]\[\large \implies x^2 = \frac{1}{2\pm \sqrt{3}}\]\[\large \implies x^2 = \frac{1}{2\pm \sqrt{3}} \cdot \frac{2 \mp \sqrt{3}}{2\mp \sqrt{3}}\]\[\large \implies x^2 = \frac{2\pm \sqrt{3}}{4-3} \]\[\large \implies x^2 = \frac{2 \pm \sqrt{3}}{1} \]\[\large \implies x^2 = 2 \pm \sqrt{3}\]\[\large \implies x = \pm \sqrt{2 \pm \sqrt{3}}\]

Answer 9

how did you go from

⟹x2=2±√3/4−3
⟹x2=2±√3/1

Answer 10

Which line?

Answer 11

how did you go from 5 to 6

Answer 12

4-3 = 1

Answer 13

All I did was simplify the denominator.

Answer 14

oh wow
im dumb
idk how i missed that

Answer 15

I think the more salient question is the step from 4 to 5

Answer 16

Did you understand what happened there?

Answer 17

yeah i understood that
