The product of two numbers is 713. the first number is 9 more than the second number. which equation can be used to find x, the greater number?

In this problem, it is given that the greater number is represented by x. With this, the smaller number which is 9 less than the greater number may be represented by x - 9. The product of the two numbers is 713 and may be expressed as 
 
                                           (x)(x -9) = 713

The equation above is the answer to the problem.
