Answer:
E. This polynomial could be factored by using grouping or the perfect squares methods.
Step-by-step explanation:
x^2 + 2x + 1
There is no greatest common factor
This is a perfect square
a^2 + 2ab+ b^2 = ( x+1)^2
We can factor this by grouping
x^2 + 2x + 1
(x^2 +x) + (x+1)
x( x+1) + x+1
Factor out x+1
( x+1) ( x+1)
This is not the difference of squares since there is no subtraction
Answer:
I believe it is B tell me if I am wrong please
Given:
A sum of money is divided between A,B and C in the ratio 9:8:7.
Total sum is 480.
To find:
The part of money A get.
Solution:
Let A, B and C get 9x, 8x and 7x respectively.
Total sum is 480.


Divide both sides by 24.


Now,



Therefore, amount received by A is 180.
Refer to the image attached.
Since, we have to divide the polynomial
by (x+2) using synthetic division.
We will divide the coefficients 4 -2 3 by -2
First term = 4 will remain same.
Second term = 
So, second term = -10
Third term = 
So, third term = 23
So, 4 -10 23 is the correct answer
So, Option 2 is the correct answer.
Answer:
5
Step-by-step explanation:
1) so lets substitute -2 as x:
y=(-2)^2+1
(-2)^2=-2*-2=4
hence
y=4+1
y=5
Hope this helps
