Question

zeros of the quadratic polynomial X square + (A + 1 )X + B are 2 and -3 then find the value of a and b​

Answer 1

Answer(s)

The discriminant of the polynomial will be equal to zero if the zeroea are equal.

b^2-4ac = 0 [When roots are equal & real]

[-(k+2)]^2-4(k+1)= 0

k^2+4+4k-4k-4=0

k=0
