If the difference between two numbers is 9 then let one number be X so the second number is (X-9)and the product of the number is 162 so
X*(X-9)=162 by finding the solution and finding the roots of the equation
X^2-9X-162=0
X^2-18X+9X-162=0
X(X-18)+9(X-18)=0
(X-18)(X+9)=0
X=18,-9 we consider only the positive value of X so the one number is 18 and the second one is “X-9=18-9=9”
Two numbers are 18,9 answers.
