Answer 1

Answer:

$\huge\tt\colorbox{lime}{Solution}$

☆Equation:-

$\frac{z(5 {z}^{2} 80)}{5z(z - 4)} = \frac{5( {z}^{2} - 16) }{(5z - 4)}$

$= \frac{(z + 4)(z - 4)}{(z - 4)}$

☆Answer:-

$= z + 4$

☆Points:-

• While in second step you have to cut (z-4)
• SO you will z+4 which will be your final answer.
• You have to arrange the equation to solve it easily.

Answer 2

Answer:

Answer is

z + 4........
