Question

Find two consecutive positive integers whose product is 72.

Answer 1

the answer 8 and 9. or -8 and -9

Explanation:

Let the smaller integer be n

→ the larger integer will be (n+1)

We are told

XXXn×(n+1)=72

XXX→n2+n−72=0

XXX→(n+9)(n−8)=0

XXXn=−9XXorXXn=8

Answer 2

8 and 9

Explanation:

8 x 9 = 72

The two consecutive positive integers whose product is 72 are 8 and 9
