Answer 2

The zeroes of the equation $3x^{2}-x-4$ are -1 and 4/3.

Step-by-step explanation:

The expression is:

$3x^{2}-x-4$

Factorize the expression as follows:

$3x^{2}-x-4=3x^{2}+3x-4x-4$

                  $=3x(x+1)-4(x+1)\\=(x+1)(3x-4)$

If (x + 1) = 0 then the value of x is -1.

If (3x - 4) = 0 then the value of x is 4/3.

Thus, the zeroes of the equation $3x^{2}-x-4$ are -1 and 4/3.
