2x² - 3xy
2(1)² - 3(1)(2)
2(1) - 3(2)
2 - 6
-4
Yes, it is true.
________________
For example,
take two integers 12 and 4
12 × 4 = 48 : product is positive
12 ÷ 4 = 3: quotient is positive
____________________
If you take -12 and 4
-12 × 4 = -48 : product is negative
-12 ÷ 4 = -3: quotient is negative
