Thay x = -2 vào đa thức Q(x), ta có:
\(Q\left(-2\right)=3\cdot\left(-2\right)^3+\left(-2\right)^4-5\cdot\left(-2\right)^2-\left(-2\right)^3-6\cdot\left(-2\right)+3\)
\(Q\left(-2\right)=3\cdot\left(-8\right)+\left(-16\right)-5\cdot\left(-4\right)-\left(-8\right)-\left(-12\right)+3\)
\(Q\left(-2\right)=\left(-24\right)+\left(-16\right)-\left(-20\right)-\left(-8\right)-\left(-12\right)+3\)
\(Q\left(-2\right)=3\)
