Answer:
(x - 7) is not a factor of (x³ + 2x² - 3x + 4).
Step-by-step explanation:
F(x) = x³ + 2x² - 3x + 4
f(x) = x - 7
if F(x) = 0 for f(x) = 0 then f(x) will be a factor of F(x)
f(x) = 0
=> x - 7 = 0
=> x = 7
F(7) = (7)³ + 2(7)² - 3(7) + 4
= 343 + 98 - 21 + 4
= 424
≠ 0
therefore (x - 7) is not a factor of (x³ + 2x² - 3x + 4).
