Question

. Find the zeroes of the quadratic polynomials 3x^3-x-4 and verify the
relation between the zero and the coefficient of the polynomial
​

Answer 1

Step-by-step explanation:

Solution:

3x^2- x- 4=0

3x^2+3x-4x-4=0

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

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

x=-1, x=4/3

Relation between the zeros and coefficient of 3x^2-3x-4.

Sum of zeros= (-1) +4/3= 1/3= -(1)/3=-b/a

Product of zeros=(-1)(4/3)= -4/3= c/a
