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 .
