Is X-1 a factor of x^5-1?
Musya8 [376]

Answer: No

Explanation:

According to factor theorem, if f(x)=0 then x is a factor of the given function or equation.

As x-1 is a factor

We equate x-1=0

x=1

Substituting in x^5-1, we have 1^5-1 =1-1=0.

Hence, it's a factor.

When coming to x^5+1, it would become 1^5+1=1+1=2

So x-1 isn't a factor of x^5+1.

ch4aika [34]
That blank is a plus sign

ok so rememmber  you can do anythiing to an equation as long as you do it to both sides

-0.3x+2=0.4x-0.1
add 0.3x to both sides
2=0.7x-0.1
add 0.1 to both sides
2.1=0.7x
times 7 both sides
21=7x
divide both sides by 7
