Q 2: If one zero of p(x)-4x2-(8k2-40k)x-9 is negative of the other, find the values of k

Answer»

Let a and b are zeroes of equation 4x^2 - (8k^2 - 40k)x - 9

Then,a = - b

Sum of zeroes = (8k^2 - 40k)/4a + b = (8k^2 - 40k)/4-b + b = 2k^2 - 10k2k(k - 5) = 0k 0, 5

Therefore value of k = 0 and k = 5
