Answer:
The answer after division is:
Step-by-step explanation:
The given question involves two mixed fractions that are being divided.
First of all, we will convert the fractions into proper fractions
When the division is performed, the second fraction is reversed
So dividing gives us:
Hence,
The answer after division is:
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
