We know that
<span>foci on x-axis-------> is a ellipse with horizontal major axis

the equation is
(x</span>²/a²)+(y²/b²)=1

major axis is th<span>e </span>x<span>-axis with length </span><span>2<span>a
2a=14--------> a=7

</span></span>minor axis is the y<span>-axis with length </span><span>2<span>b
2b=4-----> b=2

the equation is
</span></span>(x²/a²)+(y²/b²)=1------> (x²/7²)+(y²/2²)=1-----> (x²/49)+(y²/4)=1

the answer is
(x²/49)+(y²/4)=1
