The expression `1/3x^2-2` can be rewritten as `1/3(x-k)(x+k)`, where k is a positive constant . What is the value of k ?

If x-4 is a factor of x^(2)-kx+2k , where k is a constant, what is the value of k?

If kx-19=k-1 and k=3 ,what is the value of x+k ?

If (x-1)/(3)=k and k=3 , what is the value of x ?

Show that f(x) = (k-(1)/(k)-x)(4-3x^(2)) where k is a positive constant, has one and only one maximum value and only one minimum value and their difference is (4)/(9)(k+(1)/(k))^(3)

If the expression x^(3)+3x^(2)+4x+k has a factor x+5 , then what is the value of k ?

If the expression x^(3) + 4x^(2) + 4x + k has (x + 4) as a factor, then what is the value of k ?

If x=2k-1 and y=k is a solution of the 3x-5y-9=0 find the value of k.

The pair of equations 3x+y=1 (2k-1)x+(k-1)y=2k+1 is consistent for what value of k?
