Question

Find the value of k if x+3 is a factor of k x2 -7x+6k

Answer 1

Answer:

k belongs to R (real number)

Step-by-step explanation:

x+3=0

x=-3

p (x)= 2kx-7x+6k

p (-3)=- 6k+ 21 + 6k =0

Terms of k gets cancelled.

Therefore k is any real number.

k belongs to R (Real number)

Answer 2

Answer:

if x+3 is a factor of the equation

then x=-3

putting value x = -3 in the equation we get

p(-3)= k(-3)2-7(-3)+6k

=9k+21+6k

=15k+21

k=-21/15

k=7/5
