Question

if sum of square of zeroes of quadratic polynomial f(x) =x²-2x-k is 20 then find the value of k
​

Answer 1

Answer:

If sum of the squares of zeroes of the quadratic polynomial p(x) = x2 – 8x + K is 40, find the value of K. Hence, K = 12. ∴ 2, 1, 1 are the zeroes of x3 - 4x2 + 5x - 2. Hence verified.
