Answer:

the answer is (2x+ 5)^{2}

Step-by-step explanation:

because  ,solving the equation we get ,

                                          4x^{2} + 20x +25\\

                                 or,     (2x)^{2} +2.2x.5 + (5)^{2}

                                 or,     (2x +5)^{2}                 [  as,  a^{2}  + 2.a.b + b^{2}    =    (a+b)^{2}

                                                                           and here   a = 2x ,  b = 5  ]
