Can you think of two numbers whose sum is 5 and whose product is 6?
Can you think of two numbers whose sum is -12 and whose product is 11?
Can you think of two numbers whose sum is 3 and whose product is 2?
Can you think of two numbers whose sum is - 3 and whose product is -10?
Try these before you go to the next slide.
