If α and β are zeroes of the polynomial x2 - a(x + 1) - b such that (α + 1) ( β + 1) = 0, find the value of b.
If 'a' and 'b' are the non-zero distinct zeros of x2+ax+b, then the least value of quadratic polynomial x2+ax+b is
If 9 and -5 are zeroes of the polynomial x2+(a+5)x−b, then find the value of a and b. [2 MARKS]
