<em><u>HOPE IT WILL HELP YOU</u></em><em><u> </u></em><em><u>》</u></em><em><u>></u></em><em><u>☆</u></em></h2>
Step-by-step explanation:
The opposite of :-
-4=4
1= -1
-2.5= 2.5
101 = -101
1/2= -1/2
<span>[ (1 / 36) - (1 / x²) ] / [ (1 / 6) + (1 / x) ]
[ (x² - 36) / 36x² ] / [ (x + 6) / 6x ]
</span>remember that<span>:
x² - 36 = (x + 6)(x - 6)
so
[ (x+6)(x-6) / 36x² ] / [ (x + 6) / 6x ]
[ (x+6)(x-6) / 36x² ] * [ 6x / (x + 6) ]
6x / 36x² = 1 / 6x
[ (x+6)(x-6) / 6x ] * [ 1 / (x+6) ] -------------------- > </span>(x - 6) / 6x<span>
The answer is </span>(x - 6) / 6x<span>
</span>
