# Python | sympy.solve() method

With the help of `sympy.solve(expression)` method, we can solve the mathematical equations easily and it will return the roots of the equation that is provided as parameter using `sympy.solve()` method.

Syntax : `sympy.solve(expression)`
Return : Return the roots of the equation.

Example #1 :
In this example we can see that by using `sympy.solve()` method, we can solve the mathematical expressions and this will return the roots of that equation.

 `# import sympy ` `from` `sympy ``import` `*` ` `  `x, y ``=` `symbols(``'x y'``) ` `gfg_exp ``=` `x``*``*``2` `-` `4` ` `  `print``(``"Before Integration : {}"``.``format``(gfg_exp)) ` ` `  `# Use sympy.integrate() method ` `intr ``=` `solve(gfg_exp, x) ` ` `  `print``(``"After Integration : {}"``.``format``(intr)) `

Output :

Before Integration : x**2 – 4

After Integration : [-2, 2]

Example #2 :

 `# import sympy ` `from` `sympy ``import` `*`  ` `  `x, y ``=` `symbols(``'x y'``) ` `gfg_exp ``=` `x``*``*``2` `+` `36` ` `  `print``(``"Before Integration : {}"``.``format``(gfg_exp)) ` ` `  `# Use sympy.integrate() method ` `intr ``=` `solve(gfg_exp, x) ` ` `  `print``(``"After Integration : {}"``.``format``(intr)) `

Output :

Before Integration : x**2 + 36

After Integration : [-6*I, 6*I]
