Question

What is the sum of zeros of the polynomial 3x²-x -4.
please answer as fast as possible!!
thankyou ​

Answer 1

Answer:

-1 and 4/3

Step-by-step explanation:

3x²-x-4

3x²-4x+3x-4=0

X(3x-4)+1(3x-4)=0

(X+1)(3x-4)=0

X+1=0 and 3x-4=0

X= -1 and X=4/3

Answer 2

Step-by-step explanation:

$p(x) = 3x²-x-4$

$let \: the \: zeros \: of \: p(x) \: be \: α \: \& \: β$.

$Now, \: α+β = \frac{- \: coefficient \: of \: x}{coefficient \: of \: x²}$

$\implies α+β = \frac{-(-1)}{3} = \frac{1}{3}$
