Complex Roots Calculator
The calculator solves ax² + bx + c = 0 and writes a conjugate pair a + bi when the discriminant is negative.
Algebra
These pages stay with quadratics and logarithms. The calculators write the discriminant or the domain inequality with the numbers you typed.
Domain and Range of Logarithmic Functions
The calculator states the domain and range of y = log_b(x − h) + k in US interval notation.
Quadratic Formula Calculator
The calculator returns real roots only and points to the complex page when Δ is negative.
Logarithm Calculator
The calculator evaluates log_b(x) or the inverse exponential b^y.
