Question

if x-3 divides x^2-px+12 then find p​

Answer 1

Answer:

if we will divide it then the answer will come as 13

Step-by-step explanation:

(3)^2-p(3)+12=0

27-3p+12=0

27+12=3p

39=3p

39/3=p

13=p

Answer 2

hey mate

given here

if x-3 divides x^2-px+12 then find p

if x-3 is a factors of given polynomial

so,

x= 3 ,exist this polynomial ..

now,

put x= 3, this polynomial ..

we get ,

=> (3) ²-p(3)+12=0

=>9 -3p+12=0

=>3p=21

=>p= 21/3

=>p= 7

thus:

value of p will be

= 7
