Answer: Roots of quadratic polynomials are \frac{4}{3},-1

Step-by-step explanation:

Since we have given that

3x^2-x-4

First we will find the zeroes of the quadratic polynomial.

We will use "Split the middle terms":

3x^2-x-4=0\\\\3x^2+3x-4x-4=0\\\\3x(x+1)-4(x+1)=0\\\\(3x-4)(x+1)=0\\\\x=\frac{4}{3},-1

Now, Let, \alpha =\frac{4}{3},\beta =-1

Now, we will verify the relationship between the zeroes and coefficient.

Sum of zeroes is given by

\alpha +\beta =\frac{4}{3}-1=\frac{1}{3}\\\\\alpha \beta =-1\times \frac{4}{3}=\frac{-4}{3}\\and\\\\\alpha +\beta =\frac{-b}{a}=\frac{1}{3},\alpha\beta =\frac{c}{a}=\frac{-4}{3}

Hence, verified.

Roots of quadratic polynomials are \frac{4}{3},-1

hope it will be helpful to you ✌️
