find zeroes and verify relationship between their zeroes and coefficients: x³-x
Answers
Answer:
x³-x
a =1 , b = 1 and c=0
By using quadratic formula ,
x = (-b±√b²- 4ac} ÷ 2a
x = -(1) ± √1 - 0) ÷ 2
x = (1 ±√1 - 0) ÷ 2
x = 1-1÷2 or 1+1÷2
x = 0 or 1
α = 0 β = 1
Verification By Formula By calculation
α+β = -b÷a → α+β = 1+0
→ α+β = -(-1)÷1 = 1
= 1
→ αβ = c÷a → αβ = 1 x 0
= 0÷1 = 0
= 0
So, α+β = -b÷a and αβ = c÷a
