solve for x calculator

The equation solver allows to solve equations with an unknown with calculation steps : linear equation, quadratic equation, logarithmic equation, differential equation.
Equation resolution of first degree
  • equation_solver(`3*x-9`) is equal to write equation_solver(`3*x-9=0;x`) the returned result is 3.
  • equation_solver(`3*x+3=5*x+2`) returns `1/2`
Solving quadratic equations
  • Solving the equation `2*x^2-2=x^2+x` with the function equation_solver(`2*x^2-2=x^2+x`) returns two solutions separated by a semicolon [x=-1;x=2]
Solving cubic equations
  • Solving the equation `-6+11*x-6*x^2+x^3=0` with the function equation_solver(`-6+11*x-6*x^2+x^3=0`) returns three solutions.
Solve differential equation
  • equation_solver(`y'+y=0;x`) returns `[y=k*exp(-x)]` k represents a constant.
  • equation_solver(`y''-y=0;x`) returns `[y=a*exp(-x)+b*exp(x)]` a and b are constants.
