To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:

Then group terms to simplify:

Simplify any like terms:

And group together again:

You can simplify a 3 out of the first expression one more time to get:

Which would be the factored form. I hope this helps :)
Answer:
6.74
Step-by-step explanation:
may be it is .......
The answer for the first one would be 4 just divide both 16 & 4.
The answer for the second one would be -7 just divide both 63 & -9.
The answer for the third one would be -36 just multiply both 12 and -3.
The answer for the fourth one would be -120 just multiply -10 and 12.
Man tbh wth is this at this point just trow that mug out the window
