X^3+3X^2-54x
1. To factor the X^3, set the equation as x(x )(x ).
2. For the 3x^2 and -54x, find two numbers that are factors of 54, but can add up to 3. In this case the two numbers would be 9 and -6. Place the bigger number in the first part of the equation, and the -6 in the second part.
It turns out to be x(x+9)(x-6).
Factoring is used when solving a quadratic equation. Once each term and number in the equation is factored, it's easy to find the solution. For example, in this equation, the solution would look like so:
(x+9)(x-6)
x= -9
x= 6
