Question
Use synthetic division to decide whether the given number $k$ is a zero of the given polynomial function. If it is not, give the value of $f(k) .$ See Examples 2 and 3 .$$f(x)=2 x^{3}-3 x^{2}-5 x ; k=0$$
Step 1
The coefficients are 2, -3, -5. Since there is no constant term, we add a 0 at the end. So, the coefficients become 2, -3, -5, 0. Show more…
