Should be D, the one you selected
Step-by-step explanation:
Hope it helps
x^2 - 4
------------------------------
x + 7 | x^3 + 7x^2 - 4x - 28
x^3 + 7x^2
------------------
0 - 4x - 28
-4x - 28
-------------
0
Now we know that
x^3 + 7x^2 - 4x - 28 = (x^2 - 4)(x + 7)
x^2 - 4 can be factored since it is the difference of two squares.
x^2 - 4 = (x + 2)(x - 2)
The complete factoring is:
x^3 + 7x^2 - 4x - 28 = (x +2)(x - 2)(x + 7)
First you would follow the Order Of Operations:
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
Second step: You will add 6 and 4 together since addition came before subtraction in the Order Of Operations.You would get 10.
Your equation should now look like: 13-10.
Last step: You would subtract 10 from 13 since there are no other numbers
Your answer should then be: 3
