Answer 1

Answer:

a)2

Step-by-step explanation:

a = 4lm/(l+m)

(a+2l)/(a-2l) = 4lm+2l(l+m) / 4lm- 2l(l+m)

                  = 4lm+2l²+2lm / 4lm-2l²-2lm

                  =  6lm + 2l²/ 2lm-2l²

                  =   2l(3m+l)/2l(m-l)

                  =    (3m+l)/(m-l)    = p1

(a+2m)/(a-2m) = 4lm+2lm+2m² / 4lm-2lm-2m²

                       =   2m(3l+m) / 2m (l- m)

                       =       (3l+m)/(l-m)   = p2

∴p1+p2 = [(3m+l)/(m-l)]  - [(3l+m)/(m-l)]

            = [(3m+l-3l-m)/(m-l)]

            =  2(m-l)/(m-l) = 2
