(x+4)(x+4+1) = (x+1)(x+1+11)
(x+4)(x+5) = (x+1)(x+12)
x^2 + 4x+5x+20=x^2+x+12x+12
9x + 20 = 13x + 12
13x-9x = 20-12
4x = 8
x = 2
The equation of 2 secants and a circle is;
EC*ED = EB*EA
EC= X+4; ED = X+4+1 ; EB=X+1; EA= X+1+11; IN SHORT:
(x+4).(x+5) = (x+1).(x+12)
x²+9x+20 = x²+13x+12
x²+9x-x²-13x = 12-20
-4x = -8
4x = 8
and x = 2
