Use synthetic division to determine if x - c is a factor of the given polynomial function.
2x^6 - 18x^4 + x^2 - 9; x + 3
Change 3 to - 3. Plug into function.
2(-3)^6 - 18(-3)^4 + (-9)^2 - 9
2(729) - 18(81) + 81 - 9
1458 - 1458 + 72
0 + 72
72
The number 72 is not zero. So, x + 3 is not a factor of the polynomial.
Yes?
