Question

divide / simplify
z^2-25/z DIVIDE BY z-5/z+6

Answer 1

\[\frac{z^2-25}{z} \times \frac{z+6}{z-5}\]

Answer 2

\[\frac{(z-5)(z+5)}{z} \times \frac{z+6}{z-5}\]

Answer 3

\[\frac{\cancel{(z-5)}(z+5)}{z} \times \frac{z+6}{\cancel{z-5}}\]

Answer 4

z^2 - 25 z + 6 (z - 5) (z + 5) (z + 6) z^2 + 11z + 30
-------- * ------- = ------------------- = ---------------
z z - 5 (z - 5) * z z

Answer 5

so the then i cross multiply so it would the be (z+5)(z-6) right?

Answer 6

over "z" as well.

Answer 7

I hv solved it fully......
