Question

Find the value of a , if x – 1 is a zero of the polynomial p(x) = ax cube - x square +x+4​

Answer 1

Answer:

hey frnd here is your answer

Step-by-step explanation:

(x-1) is a factor if ax³-x²+x+4 means it should satisfy this polynomial.

so put x=1 in given polynomial.

ax³-x²+x+4=0

a(1)³-(1)²+1+4=0

a-1+1+4=0

a+4=0

a= -4.

so your final answer is-

a= -4.

plzz mark as brainlist.. if you get the right answer

Answer 2

Answer:

let g(x)=x-1

0=x-1

1=x

p(x)=ax³-x²+x+4

p(1)=a(1)3-(1)²+(1)+4

=a-1+1+4

=a-1+5

=a-4

=-4a
