WebIf `a` is a root of the polynomial `P(x)`, then the remainder from the division of `P(x)` by `x-a` should equal `0`. Check $$$ 1 $$$: divide $$$ 2 x^{4} - 3 x^{3} - 15 x^{2} + 32 x - 12 $$$ by $$$ x - 1 $$$. The quotient is $$$ 2 x^{3} - x^{2} - 16 x + 16 $$$, and the remainder is $$$ 4 $$$ (use the synthetic division calculator to see the steps).
