I got 0% tf..........what happen??

Those are the correct answers. Did the questions require you to show how you got the answers?

no it's was a quiz..............ugh..............thx ig

Sorry, the answers are reversed

An example of 1 worked out is.....

x2 + x – 72 = 0

x2 + 9x - 8x - 72 = 0

(x + 9) ( x - 8) = 0

x = -9

x = 8

The correct answers are:

1. -9 and 8

2. 2, 10

3. 10, -6

4. 6, -8

5. -3, -8

I will answer any more questions you have for free on chat. sorry for the inconvenience.
