Python | sympy.solve() method

  • Last Updated : 12 Jun, 2019

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]
