Question

sibtract simplify by removing a factor of 1 when possible
17ad/a^2-d^2     -          a-d/a+d

anonymous · Answer

$${{17ad}\over{a^2-d^2}} - { { a-d} \over {a+d}} ?$$

anonymous · Answer

yes

anonymous · Answer

$${ { 17 } \over { a - d} } - { { a- d} \over {a + d } }$$

anonymous · Answer

huh i dont understand what the next step is

anonymous · Answer

if your only job is to simplify it, you're done already

anonymous · Answer

what about the a^2-d^2

anonymous · Answer

yeah but i also have to subtract as well

anonymous · Answer

multiply the right one with $${ { a - d } \over { a - d } }$$

anonymous · Answer

and the left one by $${ { a + d } \over { a + d } }$$

anonymous · Answer

that will match the denominator and then you can substract

anonymous · Answer

im so lost i have no idean what you are saying so then would it be 17/a-d

anonymous · Answer

Sorry, but i need a piece of paper and a pen to really help you, maybe you should ask someone in RL to demonstrate it for you.

anonymous · Answer

the final answer would be this:
$$-{ { ( a^2 - 19ad + d^2 ) } \over { a^2 - d^2}}$$
