What is the factored term form of 2x^3+4x^2-x

Westkost [7]

Answer: $x(2x^2+4x-1)$

Step-by-step explanation:

2x³+4x²-x, first find the Greatest Common Factor (GCF), which is x. To find the GCF, look at what all the numbers have in common, and then see if it has the greatest value. Next factor out the GCF.

$x(\frac{2x^3}{x} + \frac{4x^2}{x}-\frac{x}{x} )$ Simplify each term in the parentheses.

$x(2x^2+4x-1)$

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

Answer:

$24=4k$

$k=6$

Step-by-step explanation:

For this exercise it is important to remember that "Times as great as" indicates multiplication.

Therefore, "4 times as great as" can be expressed as following:

$4k$

So, the statement "24 is 4 times as great as" indicates that 24 is equal to $4k$ .

Knowing this, you can write the following equation:

$24=4k$

In order to solve for "k", you can divide both sides of the equation by 4. Then, you get the following result:

$\frac{24}{4}=\frac{4k}{4}\\\\k=6$

Write an expression to represent each of the following sketches. Then give the value of each sketch.

zysi [14]

The sketches are illustrations of inequalities

The first sketch is: $-2 \le x \le 5$ .
The second sketch is: $3 \ge x \ge -4$

Sketch A

In sketch A, we have the following observations:

The arrow faces left (this implies less than)
The dots on -2 and -5 are closed dots (this implies less than or equal to).

Hence, the inequality is:

$-2 \le x \le 5$

Sketch B

In sketch B, we have the following observations:

The arrow faces right (this implies greater than)
The dots on -4 and 3 are closed dots (this implies greater than or equal to).

Hence, the inequality is:

$3 \ge x \ge -4$
