⇒(√z) = u ⇒4z(√z)−(√z) = 5+10(√z) ⇒(√z) (4z−1)=5(1+2(√z) ) ⇒(√z) (2(√z)−1)(2(√z)+1)=5(2(√z)+1) ⇒(2(√z)+1){(√z) (2(√z)−1)−5}=0 2(√z) +1 = 0 ⇇ not possible (√z) (2(√z)−1)−5=0 ⇒2z−(√z) = (√z) (2(√z)−1)= 5
⇒z=u⇒4zz−z=5+10z⇒z(4z−1)=5(1+2z)⇒z(2z−1)(2z+1)=5(2z+1)⇒(2z+1){z(2z−1)−5}=02z+1=0⇇notpossiblez(2z−1)−5=0⇒2z−z=z(2z−1)=5
