Undo the X first...........
Answer:
D (x-10)
Step-by-step explanation:
x^2 - 8x - 20
(x -10)(x+2)
Answer:
C. (3x)^2 - (2)^2
Step-by-step explanation:
Each of the two terms is a perfect square, so the factorization is that of the difference of squares. Rewriting the expression to ...
(3x)^2 - (2)^2
highlights the squares being differenced.
__
We know the factoring of the difference of squares is ...
a^2 -b^2 = (a -b)(a +b)
so the above-suggested rewrite is useful for identifying 'a' and 'b'.
When x = -6 the denominator = 0
There is a hole in the graph at (-6,0)
Your answer is:
2n-4
Step by step:
(n+8)+(n-12)
Rewrite and remove the parentheses
n+8+n-12
Calculate
Therefore your solution is:
2n-4
