Polynomial resultant calculator
Eliminate a variable by computing the resultant of two polynomials.
How to use this calculator
Edit Resultant(first,second,variable). The starter has resultant 3.
Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know
A zero resultant signals a common root under the relevant coefficient assumptions; parameter specializations need care.
Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
