Question

(a+b)2-(c-d)2

------------------

(a+c)2 -(b-d)2

Answer 1

(a+b)2-(c-d)2 / (a+c)2-(b-d)2

 

a$<var> \frac{a^{2} + b^{2} + 2ab - c^{2} + 2cd - d^{2}}{a^{2} +c^{2}+2ac - b^{2} -d^{2} + 2bd} </var>$

 

 $<var>-\frac{2ab + 2cd}{2ac+ 2bd}</var>$

 

$<var>-\frac{2(ab+cd)}{2(ac+bd)}</var>$

 

$<var>-\frac{(ab+cd)}{(ac+bd)}</var>$

 

Espero que te siva de ayuda.
