ohhhhh

k^2 / x -1

ohhhh

Is that -1 or +1 @scarlet adder

[scarlet adder]

Y=+1

[outer flicker]

No the question is

[outer flicker]

cool

So

k^2 / x +1

[scarlet adder]

Write it down for me pls

[outer flicker]

This?

ignore bottom

[scarlet adder]

Yhh

Go through points of intersection

[outer flicker]

well the points of intersection are when y= 0 so rearrange for x

oh you mean question B?

So

[outer flicker]

-2x +5 = (k^2/x) +1

Rearrange to form a quadratic

@scarlet adder

eg

-2x +4 = k^2/x

Then

-2x^2 +4x =k^2

-2x^2 + 4x - k^2 = 0

2x^2 -4x + k^2
