anonymous · Answer

To divide fractions, you always have to invert (flip) the second fraction and multiply

anonymous · Answer

$$\frac{z^2-49}{z^2-8z+16} * \frac{z^2-2z-63}{2z-14}$$

anonymous · Answer

Next factor each part.

anonymous · Answer

$$\frac{(z-7)(z+7)}{(z-4)(z-4)} * \frac {(z-9)(z+7)}{2(z-7)}$$

anonymous · Answer

sorry I'm so slow typing those equations

anonymous · Answer

Then see what cancels (anything in the top with anything in the denominator)

anonymous · Answer

so the z-7 will cancel. Nothing else will cancel

anonymous · Answer

Everything that is still there is your answer....$$\frac{(z-9)(z+7)^2}{2(z-4)^2}$$

anonymous · Answer

Does that make sense?

anonymous · Answer

yes
