The question is :
The sum of the distance of P(x,y) from (4,0) and (-4,0) is 10. Find the equation of locus.
Alright, I actually understand the logic of the problem, but the problem is that, I am stuck in an calculation. The calculation might be easy, but at this point of time I am not able to go about it. So plz help me to calculate.
Using the condition, The relation I get is
\(\sqrt{(x~-~4)^2+y^2}~+~\sqrt{(x~+~4)^2+y^2}~=~10\)
But using the above relation how do I proceed to the final answer?? Please give me the steps and if there are any other mistake, then plz clarify it.
The final answer given is :
\(9x^2~+~25y^2~=~225\)
Thnxx..!!
