Answer: Simplified form is \frac{4z+3}{z+2}

Step-by-step explanation:

Since we have given that

\frac{12z^2-7z-12}{3z^2-2z-8}

We need to simplify the above expression:

1) First we split the numerator :

12z^2-7z-12=0\\\\12z^2-16z+9z-12=0\\\\4z(3z-4)+3(3z-4)=0\\\\(4z+3)(3z-4)=0

Now,

2) we will split the denominator:

3z^2+2z-8=0\\\\3z^2+6z-4z-8=0\\\\3z(z+2)-4(z+2)=0\\\\(3z-4)(z+2)=0

Now, we will rewrite numerator and denominator in fraction form:

\frac{(4z+3)(3z-4)}{(z+2)(3z-4)}\\\\\text{Cancel out the common term i.e. 3z-4}\\\\=\frac{4z+3}{z+2}

Hence, simplified form is \frac{4z+3}{z+2}

12z^2 - 7z -12/ 3z^2 + 2z - 8

= (4z+3) (3z -4)/ (z+2)(3z -4)

= (4z + 3)  / (x+2)

Hope this helps
