Solve equations from their coefficients.

Use the same linear and quadratic equation formats implemented in the Calqen app, including complex quadratic roots when the discriminant is negative.

Solve ax + b = c

Choose an equation type, enter coefficients, and calculate.

Coefficient a

Coefficient b

Right side (c)

Enter coefficients and solve.

Linear equation calculator

For ax + b = c, the solver isolates x using x = (c − b) / a. The coefficient a must not be zero.

Quadratic equation calculator

For ax² + bx + c = 0, Calqen calculates the discriminant b² − 4ac. A non-negative discriminant produces real roots. A negative discriminant is returned as a complex conjugate pair.
