Question

The solution of the given differential equation $fraction numerator d y over denominator d x end fraction plus 2 x y equals y$ is

$y = c e^{x - x^{2}}$
$y = c e^{x^{2} - x}$
$y = c e^{x}$
$y = c e^{- x^{2}}$

hint Hint:

Use the separation of variables technique to solve the equation.

The correct answer is: $y equals c e to the power of x minus x to the power of 2 end exponent end exponent$

$fraction numerator d y over denominator d x end fraction space plus space 2 x y space equals space y fraction numerator d y over denominator d x end fraction space equals space y space minus space 2 x y fraction numerator d y over denominator d x end fraction space equals space y open parentheses 1 space minus space 2 x close parentheses fraction numerator d y over denominator y end fraction space equals space open parentheses 1 space minus space 2 x close parentheses d x I n t e g r a t i n g space b o t h space t h e space s i d e s comma integral fraction numerator d y over denominator y end fraction space equals space integral open parentheses 1 space minus space 2 x close parentheses d x log y space equals space open parentheses x space minus fraction numerator space 2 x squared over denominator 2 end fraction close parentheses space plus space c subscript 1 w h e r e space c subscript 1 space i s space a space c o n s tan t. log y space equals space x space minus space x squared space plus space c subscript 1 y space equals space e to the power of open parentheses x space minus x squared space plus space c subscript 1 close parentheses end exponent y space equals space space space e to the power of open parentheses x space minus x squared close parentheses end exponent space cross times space e to the power of c subscript 1 end exponent P u t t i n g space e to the power of c subscript 1 end exponent space equals space c comma therefore y space equals space c times e to the power of open parentheses x space minus space x squared close parentheses end exponent$
