Question

x2-kx+10=0 find the answer​

Answer 1

Answer:

10-k x+x^2 = 0

Multiply both sides by -1:

-10+k x-x^2 = 0

Add x^2+10 to both sides:

k x = x^2+10

Divide both sides by x:

Answer: |  

| k = x+10/x

Step-by-step explanation:

k can equal anything ://

 

if you want x to have real solutions then the determinant b^2-4ac must be greater than or equal to zero

 

 

If x is real and k is rational then k can be any number that makes the above inequality true.
