Factor the following:
2 x^3 + x^2 - 18 x - 9
Factor terms by grouping. 2 x^3 + x^2 - 18 x - 9 = (2 x^3 + x^2) + (-18 x - 9) = x^2 (2 x + 1) - 9 (2 x + 1):
x^2 (2 x + 1) - 9 (2 x + 1)
Factor 2 x + 1 from x^2 (2 x + 1) - 9 (2 x + 1):
(2 x + 1) (x^2 - 9)
x^2 - 9 = x^2 - 3^2:
(2 x + 1) (x^2 - 3^2)
Factor the difference of two squares. x^2 - 3^2 = (x - 3) (x + 3):
Answer: (x - 3) (x + 3) (2 x + 1) thus the Answer is C.
Answer:
The answer is "NOT"
Step-by-step explanation:
- To demonstrate a similar statement we want to have yet another side or some other angle, however, the third section is not proportional.
- Its sides were equivalent in proportions (yeah sure they are) + corner by the by is not given.
- There is no triangle angle provided so, that we can not enforce the SAS argument.
- It is not evidence of similarity between ABC ≈DEF.
