Question

If x-2 is a factor of x^3-5x^2+ax-7 then find the value of 'a'​

Answer 1

Answer:

solved the problem what you have given

Answer 2

Answer:a=19/2

Step-by-step explanation:

by factor theorem,

if (x-2)is a factor of p(x) then p(2)=0

so,

p(2)=(2)^3-5(2)^2+a(2)-7=0

8-20+2a-7=0

-19+2a=0

2a=19

a=19/2
