Question

If -1 is a zero of the polynomial p(x)= ax^3-x^2+x+4 then find the value of 'a'​

Answer 1

Answer:

since -1 is zero of the polynomial then, by substituting the value i.e., -1 in the equation

a * (-1)³ -(-1)²+(-1)+4 = 0

-a -1 -1 +4 = 0

-2 +4 = a

2 = a is the answer of your question

Answer 2

Answer:

a=2

Step-by-step explanation:

=p(-1)=a*(-1)^3-(-1)^2+(-1)+4=0

=p(-1)=-1a-1-1+4=0

=-a-2+4=0

=-a+2=0

=-a=-2

=a=2
