Okay this is the basic when there is a - + + = -
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:
x = 14
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 8x from both sides.
Step 3: Subtract 18 from both sides.
Step 4: Divide both sides by -2.
