Question

determine whether (x-1) is a factor of the following polynomials
x3+5x2-10x+4
x4+5x2-5x+1

Answer 1

given (x-1)

now , x-1=0
X=1

so, x^³+5x^²-10x+4

keeping value of X=1
1^³+5(1)^²-10(1)+4

1+5-10+4=0

now , 2...

x^⁴+5x^²-5x+1

keeping value of X=1

so 1^⁴+5(1)^²-5(1)+1

1+5-5+1=2

hope it help you

first equation is polynomial

but 2nd is not

Answer 2

Answer:

mark me as a brainleast

Step-by-step explanation:

given (x-1)

now , x-1=0

X=1

so, x^³+5x^²-10x+4

keeping value of X=1

1^³+5(1)^²-10(1)+4

1+5-10+4=0

now , 2...

x^⁴+5x^²-5x+1

keeping value of X=1

so 1^⁴+5(1)^²-5(1)+1

1+5-5+1=2
