Note: Consider we need to find the factor form of the given expression by taking out the GCF.

Given:

The expression is:

$-42k^3+24k^4+12k^5$

To find:

The factor form of the given expression.

Solution:

We have,

$-42k^3+24k^4+12k^5$

It can be written as:

$=6k^3(-7)+6k^3(4k)+6k^3(2k^2)$

Taking out the greatest common factor (GCF), we get

$=6k^3(-7+4k+2k^2)$

Therefore, the factor form of the given expression is $6k^3(-7+4k+2k^2)$ .

Which statement is true about the difference 2 square root of 7 − square root of 28 ?

boyakko [2]

I'll go slow:

$2\sqrt 7 - \sqrt{28}$

$=2 \sqrt 7 - \sqrt{4 \cdot 7}$

$=2 \sqrt 7 - \sqrt{4} \cdot \sqrt{7}$

$=2 \sqrt7 - 2 \sqrt 7$

$=0$

Answer: B rational and equal to 0.
