Question

If the polynomial a+9+4x-8,when divided by x+3 leaves -20 as remainder .find the value of a

Answer 1

Answer:

value of a is -9

Step-by-step explanation:

let p(x)=a+9+4x-8

and,g(x)=x+3,that implies g(x)=-3

so,by the remainder theorem p(x)/g(x)=-20:

P(-3)=a+9+4*(-3)-8=-20

P(-3)=a+9+(-12)-8=-20

P(-3)=a+9-12-8=-20

P(-3)=a+9-20=-20

P(-3)=a-11=-20

P(-3)=a=-20+11

P(-3)=a=-9(ans)
