Question

100 POINTSFactor Completely:The second equation

Answer 1

Answer:

$2x(x-4)(x+3)$.

Step-by-step explanation:

1. Write the expression.

$2x^{3} -2x^{2} -24x$

2. Divide all terms by a common term.

A common term is a term that can divide all the terms without leaving a denominator or a residue.

$\frac{2x^{3}}{2x} -\frac{2x^{2} }{2x} -\frac{24x}{2x}$

3. Rewrite.

$2x(x^{2} -x-12)$

4. Find 2 values that summed up equal -1 and multiplied equal -12.

This is because the coefficient of x is -1 and the coefficient of -12 is itself, -12.

-4 and 3 are two values that meet these requirements.

Note. This method doesn't always work for factorizing an expression, you may need to refer to other methods to solve these problems. A different method would be finding a solution for the quadratic formula throgh the quadratic formula. You may research a little more about this topic and how to use the quadratic formula on the internet.

5. Take the value we divided by on step 2 and type the found values in the following fashion.

$2x(x-4)(x+3)$

6. Express a result.

$2x(x-4)(x+3)$
