Answer 2

Answer:

The answer is

$- \frac{13}{15}$

Step-by-step explanation:

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

z = - 2

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

We have

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

Reduce the fraction with 2

We have the final answer as

$- \frac{13}{15}$

Hope this helps you
