I think this is the original equation
(i) %28x%2F%28x%2B2%29%29%5E2+=+4x%2F%28x%2B2%29+-4
step 1 - multiply both sides by (x+2)^2 to get
(ii) x^2 = 4x(x+2) -4(x+2)^2}}}
step 2 - expand both sides and combine like terms to get
(iii) x%5E2+=+-8x+-16
step 3 - set = 0 and solve by factoring steps to get
(iv) x%5E2+%2B+8x+%2B+16+=+0
step 4 - factored we get
(v) %28x%2B4%29%5E2+=+0
step 5 - solved for x we get
x%2B4+=+0
x = -4.
