Let the numbers be 5x and 6x respectively
According to the question
(5x-8)/(6x-8) =4/5
25x-40=24x-32
25x-24x=-32+40
x=8
First number =5×8=40
Second Number =6×8=48
✌✌✌✌✌✌✌

x+1=0
x=-1
substitute the value of x in equation 2x^3+9x^2+2bx+1 we get
2(-1)^3+9(-1)^2+2b(-1)+1=0
-2+9-2b+1=0
-2b=-8
b=8/2
b=4
