Answer:
[tex]g(x)=4x^2-28x+49[/tex]
[tex]=4(x^2-7x)+49[/tex]
[tex]=4(x^2-7x+(7/2)^2-(7/2)^2)+49[/tex]
[tex]=4(x-7/2)^2+4(-(7/2)^2)+49[/tex]
[tex]=4(x-7/2)^2+4(-49/4)+49[/tex]
[tex]=4(x-7/2)^2+0[/tex]
[tex]4(x-7/2)^2+0[/tex]
-------------------------------
so,
[tex]g(x)=4(x-7/2)^2+0[/tex]
----------------------------
hope it helps....
have a great day!!
