Question

if f(x) =x4-2x3+3x2-ax-b when divided by (x-1) ,the remainder is 6.then find the value of (a+b)​

Answer 1

Answer:

the value of (a+b)​ is  -4

Step-by-step explanation:

f(x) =x4-2x3+3x2-ax-b;    when divided by (x-1)  then the reminder is 6

∴ f(1)=1∧4-2×1∧3+3×1∧2-a×1-b

⇒6=1-2×1+3×1-a-b

⇒6=1-2+3-a-b

⇒6=4-2-a-b

⇒6=2-(a+b)

⇒(a+b)=2-6

∴a+b= -4
