Question

Find the zeroes of each of the following quadratic
polynomials and verify the relationship between
the zeroes and their coefficients.
(1) 3x2 - 2x - 1​

Answer 1

Step-by-step explanation:

3x^2 - 2x- 1

3x^2 - (3x-1)x - 1

3x^2-3x + 1

3x(x-1)+1(x-1)

(3x+1)(x-1)

3x+1=0 , x - 1 =0

3x= -1 , x = 1

x= -1/3 , x= 1

Now,

sum of zeroes= product of zeros

-b/a = c/a

-(-2/3) , -1/3

$\\ this \: is \: the \: answer$
