y minus 2 multiply by y stroke first (1st) order plus y two strokes of the second (2nd) order equally e to the power of x divide by (x squared plus 1)

y minus two multiply by y stroke first (1st) order plus y two strokes of the second (2nd) order equally e to the power of x divide by (x to the power of two plus one)

y-2*y'+y''=ex/(x2+1)

y-2*y'+y''=ex/x2+1

y-2*y'+y''=e^x/(x²+1)

y-2*y'+y''=e to the power of x/(x to the power of 2+1)
