If one root of ax² + bx + c = 0 be double the other, then b² = ? (please explain me)
Answers
Answer:
b² = 9ac/2
Step-by-step explanation:
let 1st root = x, then 2nd root = 2x
Now,
x+2x = -b/a , 3x = -b/a , x = -b/3a
and
x×2x = c/a , 2x² = c/a , x² = c/2a
putting x = -b/3a
(-b/3a)² = c/2a
b²/9a² = c/2a
b² = (c/2a)×9a² = 9ac/2.
