Answer:

The answer is

$- (13)/(15) \\$

Explanation:

$\frac{7z - 12}{6 {z}^(2) - 3z } \\$

z = - 2

Substitute the value of z that's - 2 into the above expression

We have

$\frac{7( - 2) - 12}{6 ({ - 2})^(2) - 3( - 2) } = ( - 14 - 12)/(6(4) + 6) \\ = ( - 26)/(24 + 6) = - (26)/(30)$

Reduce the fraction with 2

We have the final answer as

$- (13)/(15) \\$

Hope this helps you
