Step-by-step explanation:
(3x2 - 2x - 4) (2x2 + x - 3)
6x4 + 3x3 - 9x2 - 4x3 - 2x2 + 6x - 8x2 - 4x + 12
Solving like terms
6x4 - x3 - 19x2 + 2x + 12
Let us add consecutive odd numbers and try to find any relationship.
1. 1
2. 1+3 = 4 ( square of 2 i.e
)
3. 1+3+5 = 9 (
)
4. 1+3+5+7 = 16 (
)
5. 1+3+5+7+9 = 25 (
)
6. 1+3+5+7+9+11 = 36 (
)
7. 1+3+5+7+9+11+13 = 49 (
)
If we notice, the sum of the consecutive odd integers in each case is equal to the square of the place where it lies. For example, the sum of numbers in seventh place is equal to
. The sum of the numbers in the fifth line is equal to
.
Answer:
5/6
Step-by-step explanation:
The sides numbered 1,2,5 are green and 2,4,6 are even
We cannot count the 2 twice, so there are 5 unique possibilities of getting either a green or an even
There are 6 total possibilities when rolling the die 1,2,3,4,5,6
P (green or even) = green or even/ total
= 5/6
1/2, because 9/16 is closer to 8/16 which reduces to 1/2. It is not as close to 0/16 (0) or 16/16 (1)
