Use the factor theorem to determine whether the first polynomial is a factor of the second polynomial. X-3; 2x^2-4x+30

see explanation

Step-by-step explanation:

If x - 3 is a factor then x = 3 is a root and the value of the polynomial should be zero for x = 3

2 (3) ² - 4 (3) + 30 = 18 - 12 + 30 = 36 ≠ 0

hence x - 3 is not a factor of 2x² - 4x + 30
