It is given that the difference between the zeros of `4x^(2)-8kx+9` is 4 and ` k gt 0`. Then, k = ?

If one zero of f(x) = 4x^(2) - 8k x - 9 is negative of the other, find k.

If the acute angle between the lines 4x-y+7=0, kx+5y-9=0 is 45^(@) , then the value of k is

If the roots of 9x^(2)+3kx+4=0 are unequal then find the value of k

If one zero of p(x)=4x^(2)-(8k^(2)-40k)x-9 is negative of the other, find values of k .

If '4' is one of the zeroes of p(x) = x^(2) + kx -8 , then the value of k ………………

If the difference of the roots of the equation x^2 +kx+7=0 is 6, then possible values of k are (A) 4 (B)-4 (C) 8 D)-8

If the acute angle between the lines 4x-y+7=0 and kx-5y-9=0 is (pi)/(2) , then find the value of k

The angle between the lines kx+y+9=0 , y-3x=4 is 45^(@) then the value of k is
