Question

If 7x+6 is a factor of kx^2-8x-12 then find k

Answer 1

Step-by-step explanation:

7x+6=0

x= -6/7

kx2 - 8x - 12 is our polynomial

putting value of x in the polynomial

k( -6/7 )2 -8x - 12 = 0

36x/49 - 8x -12 =0

36x/49 - 8x = 12

Solving the above equation we get

356x/ 49 = 12

356x = 588

x = 588/356

now you can solve it.
