Question

If x = -4 is a solution of kx2 – 3x + 1 = 0, then find the value of k.

Answer 1

Answer:

13/8

Explanation:

x=-4 putting the value of x in the equation we get,

-8k+12+1=0

or, -8k=-13

or, k=13/8

Answer 2

Answer:

substitute values x= -4

k(-4)^2-3(-4)+1 = 16k+12+1

16k+13 = 0

16k = -13

k = -13/16
