If the sum and the product of zeros of a quadratic polynomial kx2−(k+1)x+(t−1) are 5 and 6 respectively, find the value of k × t.
If the sum of the zeros of the quadratic polynomial kx2−3x+5 is 1, write the value of k.
If one of the zero of the quadratic polynomial kx2+3x+k is 2 then find the value of k.
