(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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 .

2. Relevant equations

(x-h)^2/a^2 + (y-k)/ b^2 = 1

3. 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 .
