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)
It would be 20 percent, I believe. First you would put it into a fraction of 12\60, then you would simplify that into 3\15 then divide as shown. You end up with .2 which would be 20 percent.
Answer:
The answer to your question is 2x² - 29x + 26
Step-by-step explanation:
dividend = 6x³ - 25x² + 20x + 4
divisor = 3x + 2
2x² - 29x + 26
3x + 2 6x³ - 25x² + 20x + 4
-6x³ - 4x²
0 - 29x² + 20x
+ 29x² + 58x
0 78x + 4
-78x - 52
0 - 48
quotient = 2x² - 29x + 26
remainder = -48
Result = 2x² - 29x + 26 - 48/6x³ - 25x² + 20x + 4
The answer to your problem is: 122.32
