Answer: x^3 - 1 = (x - 1)(x^2 + x + 1)
Explanation:
This is a type of factorizing called the sum or difference of 2 cubes:
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
The sum of the cubes is factored as:
a^3 + b^3 = (a + b)(a^2 - ab + b^2)
In this case, we have: x^3 - 1 so follow the rule above.
x^3 - 1 = (x - 1)(x^2 + x + 1)
Answer:
They are asking what line meets that number (5) which should be Line A
Step-by-step explanation:
Answer:
the answer is -9
Step-by-step explanation:
3(2 - 5)
6 - 15
-9
Answer:
The correct answer is B(2)
Step-by-step explanation:
I did it and somehow got it right.
3x < -6
x < -6/3
x < -2
Therefore, the solution set is {x | x < -2}.
