Polynomial Evaluator

Evaluate a cubic polynomial ax³ + bx² + cx + d at any value of x. Useful for quickly checking polynomial outputs in algebra, calculus, and engineering curve analysis without manual arithmetic.

Coefficient a (ax³)

Coefficient b (bx²)

Coefficient c (cx)

Constant d

Value of x

Fill in the required fields to see your result.

Algebra

Linear Equation Solver

Solve any single-variable linear equation of the form ax + b = 0 for the unknown x. The simplest non-trivial equation in algebra, this is the building block for systems of equations, slope-intercept lines, and almost every applied modelling problem.
