  1. Evaluate expression : ( x + 2 )


    Step 1 :  

    The given expression is ( x + 2 )2


    Here, a= x and b =2



    Step 2 :  

    Applying the formula: (a+b)2= a2 + 2ab + b2


    ( x + 2 )2 = x2 + 2(x)(2) + (2)2 = x2 + 4x + 4



    Step 3 :  

    Perfect square trinomial expression: x2 + 4x + 4.



    Answer  :  

    x2 + 4x + 4.



  2. Evaluate expression : (x+4)2


    Step 1 :  

    The given expression is ( x + 4 )2


    Here, a= x and b =4



    Step 2 :  

    Applying the formula: (a+b)2= a2 + 2ab + b2


    ( x + 4 )2 = x2 + 2(x)(4) + (4)2 = x2 + 8x + 16



    Step 3 :  

    Perfect square trinomial expression: x2 + 8x + 16.



    Answer  :  

    x2 + 8x + 16.
