Answer 2

Answer:

3X²-X-4

==> 3X²-4X+3X-4

==> X(3X-4)+1(3X-4)

==> (3X-4) = 0 AND X+1 = 0

==> 3X = 4 AND X = -1

==> X = 4/3 AND -1

VERIFY :-

FROM POLYNOMIAL 3X²-X-4

A = 3 , B = -1 , C= -4

SUM OF ZERO'S = -B/A

==> 4/3 - 1 = -(-1)/3

==> 4-3/3 = 1/3

==> 1/3 = 1/3

PRODUCT OF ZERO'S = C/A

==> 4/3×-1 = -4/3

===> -4/3 = -4/3
