Question

If a polynomial p(X)=X4-2x3+3x2-ax+8 is divided by (x-2), it leaves a remainder 10 .find the value of a

Answer 1

as we know in this question we have to find the value of a

by solving this question we get the value of a =5

Answer 2

Answer:

Let g(x)=x-2

g(x)=0

》x-2=0

》x=0+2

》x=2

Then,

p(2)=0

》2×4-2×3+3×2-a×2+8=0

》8-6+6-2a+8=0

》16-2a =0

》-2a=0-16

》-2a=-16

》2a=16

》a=16÷2

》a=8

Value of a is 8.
