Question

If x equals to -A is a solution of x square - 3 x + K is equal to zero then find the value of k​

Answer 1

Answer: k=1

Step-by-step explanation:y=

3x+1= 0.-------------------(i)

ky=(k-2)x+2

y=[(k-2)]/k +(2/k)

the two are parallel.

3 = (k-2)/k

3k=k-2, by cross-multiplication

2k=-2

k=-1

check

-3x+y+2=0

y=3x-2
