Step-by-step explanation:
x³ - 4x² + x - 4
= x²(x - 4) + (x - 4)
= (x² + 1)(x - 4).
Since the quadratic factor (x² + 1) is irreducible any further, this is our answer.
Answer:
no
Step-by-step explanation:
Substitute x = 3 into the equation and if the result is 0 then it is a solution
y = 5(3) + 3 = 15 + 3 = 18 ≠ 0
Then (3, 0 ) is not a solution to the equation

For this case, the first thing we must do is define variables.
We have then:
t: cost of the torch
b: cost of the battery
The cost of both items in £ is given by:
Therefore, we have the following equation:
Then, we know that:
The torch costs eleven times as much as the battery.
Substituting equation two in the equation we have:
Clearing the value of b we have:
Answer:
The cost of the battery is 0.43 £
