Answer:
(a−b),a,(a+b) are the zeros of 2x
3
−6x
2
+5x−7
Sum of zeroes =
(coefficient of x
2
)
−(coefficient of x)
a−b+a+a+b=
2
−(−6)
=3
⇒3a=3
⇒a=1
Answer:
The answer is undifined
Step-by-step explanation:
Given cubic polynomial 2x³- 5x+7
Compare given equation with ax³+bx²+ cx + d = 0
⇒ a = 2, b = 0, c = -5 and d = 7
sum of the zeros = -b/a
= 0/2 = undifined
