How did they do this? What's the step

This is the original equation [ (8 / (x² - 4)) - (x / (x - 2)) ] then they got this [ (8 - x(x + 2))/(x² - 4) ] What step did they take to get there? Thanks to anyone that helps.-Given: 8/(x² − 4) −

Como puedo resolver la siguiente integral por partes ayuda!/ how can I integrate this help me!∫x cos x/2 dx

porfavooor!/pleasssse!-pardoname, yo se un poco espanol. ∫x cos x/2 dx=∫Udv cuando U = x,dv = cos(x/2)sx du = dx,V = 2sin(x/2) ∫Udv = UV - ∫Vdu =2x*sin(x/2) - ∫2sin(x/2)dx =2x*sin(x/2) + 4cos(x/2))

What is √12 + 2 / √12 - 2

Write √12 + 2 / √12 - 2 in the form a+b √3 where a and be are integers. The answer is 2+√3, but how do you get to this answer?-√12 + 2 ********** √12 - 2 √12 + 2......√12 + 2 **********X********** √1

Solve for x!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

2^x+2=5^x-5 help!!!!-2^(x+2)=5^(x-5) (x+2)log2 = (x-5)log5 (x+2)/(x-5) = log5/log2 = 2.3219 x+2 = 2.3219x - 11.6906 13.6906 = 1.3219x x = 10.2955-2^(x + 2) = 5^(x - 5) (x + 2) * ln(2) = (x - 5) * ln(
