Answer:
5x^2−10x−2
Step-by-step explanation:
I hope this is what you are looking for I just added (5x^2 – 9) + (-10x + 7)
Step-by-step explanation:
So Scientific Notation is like this.
Ya got a big number that has of 0s . Let's just throw out 69,000,000,000,000
You take the other numbers that arent 0s. Take the first number and put a "." in between it and the second number. So, in this case, you have 6.9, like this.
You then count the number of 0s and +1. So in this case, you'll have 12+1. Which is 13.
You then take the 6.9 and note it with a *10. You then take the 13 and put it on the 10 as an exponent. So in the end youll have 6.9*10^13.
Hopefully, this helps.
