Question

hey guys plzz help me to solve this ques.

Answer 1

(-2)³+a(-2)+b=0,

-8-2a+b=0,

then

-2a+b=8,........eq(1),


(-3)³+a(-3)+b=0,


-27-3a+b=0,


then

-3a+b=27,............eq(2),


subtract eq(1) from eq(2), we get


-a=27-8,


-a=19,


then

a=-19,


put this value in eq(1), we get


-2(-19)+b=8,


38+b=8,


then


b=8-38,

b=-30
