+22 okay to whoever helps me witth these I thank you greatly 
The side lengths of a cyclic quadrilateral ABCD are provided in the diagram. Find \(BD^2\)
[asy]
size(150);
pair A,B,C,D;
A=dir(10);
B=dir(46);
C=dir(118);
D=dir(210);
draw(D--A--B--C--D--B);
draw(circle(origin,1),blue);
dot("$A$",A,A);
dot("$B$",B,B);
dot("$C$",C,C);
dot("$D$",D,D);
label("$1$",A--B,-(A+B)/2);
label("$2$",B--C,-(B+C)/2);
label("$3$",C--D,(C+D)/2);
label("$4$",D--A,(D+A)/2);
