If the polynomial x^2 + bx + c has exactly one real root and b = c + 2, find the value of the product of all possible values of c .
If the polynomial x^2 + bx + c has exactly one real root and b = c + 2,
find the value of the product of all possible values of c .
One root means the discriminant equals zero. b2 – 4ac = 0
(c + 2)2 – (4)(1)(c) = 0
c2 + 4c + 4 – 4c = 0
c2 + 4 = 0
Ruh roh, this is going to result in an imaginary number.
Either there's no solution or I'm doing something wrong.
