If c > a > 0 and a - b + c = 0, find the larger root of ax^2 + bx + c = 0.
The first one I thought of is x2 + 3x + 2 = 0
(x + 1)(x + 2) = 0
x = – 1
x = – 2
The larger root: – 1 is larger than – 2.
The criteria c > a > 0 and a – b + c = 0 also work for x2 + 4x + 3 (x + 1)(x + 3)
and x2 + 5x + 4 (x + 1)(x + 4)
and x2 + 6x + 5 (x + 1)(x + 5)
and x2 + 7x + 6 (x + 1)(x + 6)
and you can keep going as long as you want to.
