### Instruction: help me answer this question Length of major axis 26, foci (±5, 0), think step by step
### Assistant: The major axis is along the x-axis, the length of the major axis is given as 26, and the foci are given. So, the equation will be of the form x2/a2 + y2/b2 = 1. Here, 2a = 26, a = 13, and c = 5. Using a2 = b2 + c2, b2 = 169 – 25 = 144. So, the equation of the ellipse is x2/169 + y2/144 = 1. , The answer is The equation of the ellipse is x2/169 + y2/144 = 1
