is x - 2 is a factor of p(x) = x^4 - 3x^2 + 2x - 8?

Answer 1

yes

Answer 2

p(x)=(x−2)(x+2.314596)

Answer 3

so yes

Answer 4

There is a neat trick you can use in order to find out whether something is a factor or not.

for a function f(x) , and a factor (x+a) The remainder is f(-a) , if the remainder ends up being zero, then (x+a) is a factor.

as we have (x-2) , we have to plug -(-2) into the function.

So we have: \[p(2) = 2^4 - 3(2^2) + (2*2) - 8\]

=\[p(2) = 16 - 12 + 4 - 8 = 0\]

x-2 is a factor! c:
