If P (x,y) be any point on ` 16x^(2) + 25y^(2) = 400` with foci ` F_(1) (3,0) and F_(2) (-3,0)` then ` PF_(1) + PF_(2)` is

P(x,y) is any point on ellipse 16x^(2)+25y^(2) =400 . If F_(1)-=(3,0) and F_(2) -=(-3,0) , then prove that PF_(1)+PF_(2) is constant and find its value .

The foci of 16x ^(2) + 25 y^(2) =400 are

The foci of 16x ^(2) + 25 y^(2) =400 are

If P(x,y) is any point on the ellipse 16x^(2)+25y^(2)=400 and f_(1)=(3,0)F_(2)=(-3,0), then find the value of PF_(1)+PF_(2)

If P(x ,y) is any point on the ellipse 16 x^2+25 y^2=400 and f_1=(3,0)F_2=(-3,0) , then find the value of P F_1+P F_2dot

If P(x ,y) is any point on the ellipse 16 x^2+25 y^2=400 and F_1=(3,0)F_2=(-3,0) , then find the value of P F_1+P F_2dot

If P(x ,y) is any point on the ellipse 16 x^2+25 y^2=400 and f_1=(3,0)F_2=(-3,0) , then find the value of P F_1+P F_2dot
