Answer:

Points L, M, and N are collinear with M between L and N. LM = 2x + 8 and MN is one half the length of LM. If LN = 42, write and solve an equation to find x.

The polynomial p(x)=x^3-7x-6 has a non-factor of (x+1) rewrite p(x) as a product of linear factors.
In-s [12.5K]

Answer:

Using synthetic division suffices to answer your question:

Step-by-step explanation:

Synthetic division is the process by one reduces a large polynomial in your case x^3-7x-6 by a binomial in your case (x+1).

To do so one does the following:

\begin{array}{cccccc}-1|& 1&0&-7&-6\\ & &-1&1&6 \\& 1&-1&-6&0  \end{array}

Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:

(x^2-x-6)

Which can be factored in the following, and I will provide the complete factorization as well:

p(x)=(x+1)(x-3)(x+2)

N76 [4]

Answer:

  14.  -5√30 +3√2

  15.  18√5 -30√3

Step-by-step explanation:

You can multiply radicals using ...

  (√a)(√b) = √(ab)

And you can simplify radicals using ...

  √(a²b) = a√b

_____

14. Using the distributive property, then simplifying the radicals, we have ...

  \sqrt{3}(-5\sqrt{10}+\sqrt{6})\\\\=-5\sqrt{3\cdot10}+\sqrt{3\cdot6}\\\\=-5\sqrt{30}+\sqrt{3^2\cdot2}\\\\=\boxed{-5\sqrt{30}+3\sqrt{2}}

__

15. Similarly, ...

  -2\sqrt{15}(-3\sqrt{3}+3\sqrt{5})\\\\=6\sqrt{15\cdot3}-6\sqrt{15\cdot5}\\\\=6\sqrt{3^2\cdot5}-6\sqrt{5^2\cdot3}\\\\=\boxed{18\sqrt{5}-30\sqrt{3}}
