Find the zeros of polynomial 6x² - 3 - x |
|
Answer» Answer: Step-by-step explanation: We have, f(x)=6x 2 −3 → f(X)=( 6 x) 2 −( 3 ) 2
→ f(x)=( 6 x− 3 )( 6 x+ 3 ) The zeros of f(x) are GIVEN by f(x) =0 ie., ( 6 x− 3 )( 6 x+ 3 )=0 ⇒ 6 x− 3 =0 or, 6 x+ 3 =0 ⇒ x= 6
3
or, x= 6
− 3
⇒ x= 2
1 or x=− 2
1
Hence, the zeros of f(x)=6x 2 −3 are: α= 2
1 = and β=− 2
1
Now, SUM of the zeros = α+β= 2
1 +(− 2
1 )=0 Sum of the zeros = - COEFFICIENT of x 2
Coefficient of x
∴ - Coefficient of x 2
Coefficient of x =− 6 0 =0 Also, Product of the zeros = αβ = 2
1 × 2
−1 = 2 −1
and, ∴ Product of the zeros= Coefficient of x 2
Constant term = 6 −3 = 2 −1
Hence verified.I HOPE it helps you ✅✅ |
