Okay, it's wrong because they forgot to do -2 times 3x.
The correct answer is
-2x-8
Hope i got is correct!
Apply Pythagoras:
length = sqrt( (10--4)² + (6-3)² ) = sqrt(205)
5x³ + 8x² - 7x - 6
1)
x + 2 is a factor because when using synthetic division, the remainder is zero.
-2 | 5 8 -7 -6
<u>| ↓ -10 4 6 </u>
5 -2 -3 0 ← remainder is zero
2)
x + 2 is not a factor because when using synthetic division, the remainder is not zero.
-1 | 5 8 -7 -6
<u>| ↓ -5 -3 10 </u>
5 3 -10 4 ← remainder is not zero
7.7 because it is more specific into the whole number but not just that and the decimal
Answer:I think 11 will be the answer
