4x^(2)+28x+41

If x ge 4, A^(2)=x^(2)+12x + 36 , and B^(2)=4x^(2)-28x+49 , then (A+B)^(2)=

let P(x)=x^(2)+bx+c, wherer b and c are interger.if P(x) is a factor of both x^(4)+6x^(2)+25 and 3x^(2)+4x^(2)+28x+5 find value of p(1)

Let p(x)=x^(2)+bx+c, where b and c are integers.If p(x) is a factor of both x^(4)+6x^(2)+25 and 3x^(4)+4x^(2)+28x+5 find the value of p(1).
