By Team Edtoolkits · Study & learning
Solve linear, quadratic and polynomial equations (real and complex roots) and 2×2 or 3×3 linear systems, with the working shown and a graph of the roots.
Use the guide alongside the working tool.
Open Equation Solver →Get started
Choose the type: linear, quadratic, polynomial or a system of equations.
Adjust and explore
Enter the numbers in front of each term (the coefficients).
Save and share
Read the roots, follow the working, and check the graph where the curve crosses zero.
Privacy and limits
You enter coefficients rather than typing a free-form equation. Polynomials up to degree 10 are solved numerically in double precision (about 12 correct digits; very close repeated roots may show slight rounding). Systems must be 2×2 or 3×3. Nothing you enter leaves your device.
