Question

examine whether x-1 is a factor of the following polynomial 2xcube-5xsquare+x+2​

Answer 1

Answer:

no x-1is not the factor because the remainder is not 0

Answer 2

Explanation:

x=-1/3

p(x)= 27x^3-ax^2-x+3

p(-1/3)= 27(-1/3)^3-a(-1/3)^2-(-1/3)+3=0

p(-1/3)= 27×-1/27-a/9+1/3+3=0

p(-1/3)= -1 -a+2+27=0

p(-1/3)= 30+a=0

p(-1/3)= a= -30

a= -30 ANS.
