TAKING (1/(X+2)) THEN RATIONALIZE IT I.E MULTIPLY BOTH THE DENOMINATOR AND THE NUMERATOR WITH THE OPP. OF DENOMINATOR.WHICH WILL BE(X-2). ON MULTIPLYING THE ANSWER WILL BE (X-2)/(X2-4)
THEN DO THE SAME WITH THE OTHER TERM AND U WILL GET(X+2)/(X2-4)
THEN JUST SUBTRACT THEM AND U WILL GET THE ANSWER -6/(X2-4)

(1/(x+2))_(1/(x-2))=(x-2)-(x+2)÷(x+2)(x-2)=2x-4÷x^2-2x+2x+x^2=2x-4÷2x^2=2(x-2)÷2(x)^2=x-2÷x^2=x-2/x^2
