Question

how would I stetch the graph if it passes through (-4,5) and the zeros are 2+sqroot3 and 2-sqroot3 ?

Answer 1

How would I determine the equation? *

Answer 2

OK. So, the zeroes of a quadratic function can be found from the factoring, so they are (x-r)(x-s) where r,s are the roots. So we need (x-2-sqrt(3))(x-2+sqrt(3)).

Answer 3

That's the equation once you FOIL it.

Answer 4

\[(x-2-\sqrt3)(x-2+\sqrt3)\]

Answer 5

If that's any clearer.

Answer 6

oh okay, then I foil it?

Answer 7

or expand?
