In some word problems, where there is an x2, AND IT DOES NOT CANCEL OUT, we have to solve it like a quadratic.
HOW?
Set it equal to ZERO and factor it!!
Examples:
1) Find two consecutive integers whose PRODUCT is 90.
2) Find two consecutive odd integers whose PRODUCT is 99.
3) Find two NEGATIVE consecutive integers whose product is 72.

GREATER/LESSER WORD PROBLEMS:
Examples:
1) The greater of two numbers is three times the lesser. If the greater number is decreased by 12, the result is 6 more than the lesser. Find the numbers.
2) The greater of two numbers is 13 more than 2 times the lesser. Nine times the greater number is 5 more than 4 times the lesser. Find the numbers.
3) Find three consecutive integers such that the sum of the first two integers is 13 less than the greatest integer.
4) Find two consecutive integers whose product is 24 more than the square of the lesser integer.
