Homework Statement
an ellipse has the vertices (+&-4, 0)and the point (1,2) lies on the ellipse. find the standard form of the equation of the ellipse .
Homework Equations
(x-h)^2/a^2 + (y-k)/ b^2 = 1
The Attempt at a Solution
(x-0)^2/(4)^2 + (y-0)/b^2 = 1
(1-0)^2/16 + (2-0)^2/b^2 = 1
16b^2 ( 1/16+4/b^2=1)
**b^2 +64/16 = 16b^2
** b^2/16 + 4 = b^2
**b=b/4 + 2
note: *** is where i think i made my mistakes.
so will anyone tell me, what i did wrong and help me with how to finish this problem, thanks .
