The product of two consecutive positive even numbers is 528. What are the numbers? (Enter solutions from smallest to largest.)

Question

and

Answer 1

x(x+2)=528
x^2+2x=528.
At this point complete the square
(x+1)^2=529
x+1=+/-square root 529
x=-1+/-23
The two solutions are 22,-24. Remember that is wants even integers.
22(24)=528
