Answer:
Explanation:
Correct Question :-
Find the remainder p(x) = x³ - 6x² + 2x - 4 divided by q(x) = 1 - 2x
Answer :-
The remainder is - 35/8 when p(x) = x³ - 6x² + 2x - 4 divided by q(x) = 1 - 2x
Solution :-
p(x) = x³ - 6x² + 2x - 4 divided by q(x) = 1 - 2x
First find the zero of 1 - 2x
To find the zero of 1 - 2x equate it to 0
1 - 2x = 0
- 2x = - 1
x = - 1/-2
x = 1/2
By Remainder theorem p(1/2) is the remainder when p(x) = x³ - 6x² + 2x - 4 divided by q(x) = 1 - 2x
p(x) = x³ - 6x² + 2x - 4
Substitute x = 1/2
p(1/2) = (1/2)³ - 6(1/2)² + 2(1/2) - 4
= 1/2³ - 6(1/2²) + 1 - 4
= 1/8 - 6(1/4) + 1 - 4
= 1/8 - 3(1/2) - 3
= 1/8 - 3/2 - 3
Taking LCM
= 1/8 - 3(4)/2(4) - 3(8)/1(8)
= 1/8 - 12/8 - 24/8
= 1/8 - 36/8
= - 35/8
Therefore the remainder is - 35/8 when p(x) = x³ - 6x² + 2x - 4 divided by q(x) = 1 - 2x
Answer:
38/4 is your answer
