Answer:
x>-3
Step-by-step explanation:
Answer:
x = 1 or x = ± i
Step-by-step explanation:
Note the sum of the coefficients
1 - 1 + 1 - 1 = 0
This indicates that x = 1 is a root, thus (x - 1) is a factor
Using long division or synthetic division, then
x³ - x² + x - 1 = (x - 1)(x² + 1), thus
(x - 1)(x² + 1) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x² + 1 = 0 ⇒ x² = - 1 ⇒ x = ±
= ± i

Answer:
145%
Step-by-step explanation:
Answer:
Subtract 60 from the sum of 8e and 20 when e=7
8e +20
8(7) + 20
56+20=76
76-60=16
