$f(x) = (x - 3)^2 + 17$

$Develop: f(x) = (x^2 - 6x + 9 ) + 17 = x^2 - 6x + 26$

$(a+b)^2=a^2+b^2+2ab$ ,this is the prequist knowledge that u must know ..!!

Now by applying this identity u can open this eq:
$(x-3)^2+17$ in this way..
$x^2+(3)^2+2(x)(3)+17$
now this can be simplified as:
$x^2+9+6x+17$
which can be further simplified as:
$x^2+6x+26$
this is ur answer!!
