Differential equation:
Equation y'=-1+y/x
Equation y'=2+4*y/x+y^2/x^2
Equation x^2*y'=x*y+y^2
Equation y''+y=7*e^x
Identical expressions
y'=(x^ two +x*y+y^ two)/x^ two
y stroke first (1st) order equally (x squared plus x multiply by y plus y squared ) divide by x squared
y stroke first (1st) order equally (x to the power of two plus x multiply by y plus y to the power of two) divide by x to the power of two
y'=(x2+x*y+y2)/x2
y'=x2+x*y+y2/x2
y'=(x²+x*y+y²)/x²
y'=(x to the power of 2+x*y+y to the power of 2)/x to the power of 2
y'=(x^2+xy+y^2)/x^2
y'=(x2+xy+y2)/x2
y'=x2+xy+y2/x2
y'=x^2+xy+y^2/x^2
y'=(x^2+x*y+y^2) divide by x^2
Similar expressions
y'=(x^2+x*y-y^2)/x^2
y'=(x^2-x*y+y^2)/x^2

Differential equation y'=(x^2+x*y+y^2)/x^2

The teacher will be very surprised to see your correct solution 😉
