let the two consecutive integers be n and n+1.
The produst is n(n+1) and the sum is n+(n+1)
Now piece it together.
First Step - Before Posting, decide how much of your own work you are planning to show.
A = First Integer, the least of the two.
B = Next Integer greater than A. Hey, we don't need B, since B = A+1
"the product of two consecutive integers"
A*B or A*(A+1)
"10 less than four times their sum"
Stare at those until the translation soaks in. You will see it.
