Answer:

1. $-m(-8n^2-7n+1)$

2. $(2w+7c) (v+7c)$

5. (q+3r)(q^2-3qr+9r^2)

7. x= - 4/7, 1/9

See below for additional problems and help.

Step-by-step explanation:

To factor polynomials, look for patterns and greatest common factors. When you remove these factors, write the factor and what remains.

For example:

$8mn^2+7mn-m\\-m(-8n^2-7n+1)$

Notice the term $(-8n^2-7n+1)$ is left and is the term when the expression is divided by -m.

2. Factor by grouping is similar. Pull out factors within pairs of term. Separate the terms by parenthesis. If the quantities in the [parenthesis are the same, the factoring has been successful.

$(2vw + 7cv) + (14cw + 49c^2)\\v(2w+7c)+7c(2w+7c)$

Notice that (2w+7c) is the same. The factoring is complete. The factors are:

$(2w+7c) (v+7c)$

3 - 6 is similar using specific forms for factoring. To find the forms, look in your notes or at resources on online. Here is one example.

4. A sum of cubes has the form

$a^3 + b^3 = (a + b)(a^2 -ab + b^2)$ .

To use this form, take the cube root of each term. a = q and b=3r.

The factors are $(q+3)(q^2-3qr+9r^2)$

7-9 all involve factoring and then solving. You solve by setting the factors equal to 0.

7. (7x+4)(9x-1) = 0

(7x+4) = 0 (9x-1)=0

7x=-4 9x = 1

x= - 4/7 x = 1/9

What is the correct factorization of:<br> x? - 11x + 18

Dominik [7]

9514 1404 393

Answer:

x² -11x +18 = (x -9)(x -2)

Step-by-step explanation:

The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.

18 = (-1)(-18) = (-2)(-9) = (-3)(-6)

The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...

x² -11x +18 = (x -9)(x -2)

Let p, q, and r represent the following statements"

Nitella [24]

In logic, own symbols are used in order to be able to represent the relations between propositions in a general and independent way to the proposition, in order to be able to find the relationship process that operates in the communicated message, the propositional logic.

For this purpose there are, among others, the following logical operators: conjunction (and) ∧, disjunction (or) ∨, denial (not) ¬, conditional (if - then) ⇒ and double conditional (if and only if, iff) ⇔.

So for this case we have:

Answer

a) Sam had pizza last night if and only if Chris finished her homework.

p⇔q

b) Pat watched the news this morning iff Sam did not have pizza last night.

r⇔¬p

c) Pat watched the news this morning if and only if Chris finished her homework and Sam did not have pizza last night.

r⇔(q∧¬p)

d) In order for Pat to watch the news this morning, it is necessary and sufficient that Sam had pizza last night and Chris finished her homework.

r⇔(p∧q)

e) <em>q ⇔ r</em>

Chris finished his homework if and only if Pat watched the news this morning

f) <em>p ⇔ (q ∧ r)</em>

Sam had pizza last night if and only if Chris finished his homework and Pat watched the news this morning

g) <em>(¬p) ⇔ (q ∨ r) </em>

Sam didn't have pizza last night if and only if Chris finished his homework or Pat watched the news this morning

h) <em>r ⇔ (p ∨ q) </em>

Pat watched the news this morning if Sam had pizza last night or Chris finished his homework
