Question

prove that x-2 is a factor of 2power3 - 3power2 -17x +30​

Answer 1

Answer:

if x-2 is factor of polynomial p(x)

then remainder 'g(x)' will be 0

Step-by-step explanation:

so,

p(x)=2^3-3^2+17x+30

g(x)= 0

zero of polynomial x-2

equate to 0

so,

x-2=0

x=2

p(2)=2^3-3^2-17x+30

= 8-9-17(2)+30

= -1-34+30

=-35+30

=-5

hence remainder is not zero x-2 is not factor of p(x)
