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:
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
