With some simple rearrangement, we can rewrite the numerator as
Then factorizing the difference of squares, 
, we end up with
Combine like terms. Remember that like terms are terms that are completely the same excluding the coefficient.
7x-8x=-1x
Final answer: -x+5
So say we have the number: 54,321
The 5 would be worth 50,000 meaning it's in the ten thousands place.
The 4 would be worth 4,000 meaning it's in the thousands place.
.
The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place
.
Hope that helps :)
Answer:

Step-by-step explanation:
4.1
= 4 + 1/10
= 4 1/10
Hope you understand!
Hello :
<span>y = 3x2 + 24x - 1
= 3(x²+8x) -1
= 3 (x² +2(4)(x) +4²- 4² ) -1
= 3((x+4)² -16)-1
y = 3(x+4)² - 49
</span><span>the line of symmetry is : x= - 4</span>
