Hello,
Let's have x be a positive number and the next to be x+2. Now we can set up an equation to be:
x(x+2)=x+(x+2)+41 Expand this out to:
x^2+2x=2x+43 Subtract 2x from both sides to get:
x^2=43 Square root both side to get:
x=+-sq rt 43
There we go.
Make sense?

The product of two positive consecutive integers is 41 more than their sum. Find the integers.

Let the first number be F

Then the second = F + 1

Their product = F(F + 1) = F%5E2+%2B+F, and their sum is: F + F + 1 = 2F + 1

Since their product is 41 more than their sum, then we have:

F%5E2+%2B+F+=+2F+%2B+1+%2B+41

F%5E2+-+F+-+42+=+0

(F + 6)(F - 7) = 0

Ignore F + 6 = 0, because F = - 6, and we're looking for a positive number. Therefore, F, or the 1st number is 7, and so, the numbers are highlight_green%287_and_8%29
