The sum of two numbers is 53 and the difference is 15 . What are the numbers?

34 and 19.

Step-by-step explanation:

Since the sum of the two numbers is 53, x+y=53. Since the difference is 15, x-y=15.

Adding x+y=53

and       x-y=15,

The ys cancel, leaving 2x=68, or x=34. Therefore, 34-y=15, or y=19.

the answer will be b x² +x-1
