Question

Check whether p(x) is a multiple of g(x) or not :

(i) p(x)=x³-5x²+4x-3. g(x)=x-2
(ii)p(x)=2x³-11x²-4x+5. g(x)=2x+1​

Answer 1

Answer:

1)-7

2)-11/2

Step-by-step explanation:

i) x-2=0

x=2

p(2)=2^3-5×2^2+4×2-3

8-20+8-3

16-23

-7

2)2x-1=0

x=1/2

p(1/2)=2×1/8-11×1/4+5

1/4-11/4-2+5

1-11/4-3

-10/4-3

-5/2-3

-5-6/2

-11/2
