Answer:

2 ( x+3) (x+1)

Step-by-step explanation:

2x^2+8x+6

Factor out a 2

2(x^2 +4x+3)

Factor in side the parentheses

What multiply to 3 and adds to 4 (3(1=3 3+1 =4)

Write in radical form

Studentka2010 [4]

Step-by-step explanation:

I'll do one for you.

Using the formula for turning exponents into radicals

$(b) {}^{ \frac{x}{y} } = \sqrt[y]{b} {}^{x}$

where b is the base

This means that the numerator in the exponet form becomes the power under the radical in radical form and

the denominator in exponet form becomes the nth root in radical form.

For example 5,

$(5) {}^{ \frac{ - 3}{5} }$

That becomes in radical form

$\sqrt[5]{5 {}^{ - 3} }$

or if you want to write it using positive exponents

$\frac{1}{ \sqrt[5]{5 {}^{3} } }$

I'll do one more for you

For example 6,

$11 {}^{ \frac{4}{3} }$

That becomes in radical form

$\sqrt[3]{11 {}^{4} }$

I need help with this I need shown work too it won’t count if I am not showing my work

iogann1982 [59]

The answer is 7x + 3

First, you have 3x-1 + 2x+1
Combine like terms and the 1’s cancel each other out. You are left with 5x.

Then, you add x+2 + x+1
Combine like terms and you have 2x+3

Add 5x + 2x+3 and you have 7x +3

I’m bad at explaining, so here are the steps.
