Complete the steps to factor the polynomial by grouping. P(x) = x3 + 5x2 – x – 5 P(x) = x2 (x + ) – (x + 5) P(x) = (x2 – )(x + 5) P(x) = (x – )(x + 1)(x + )

Answer 1

Answer:

Answer:

$p(x)=(x+5)(x-1)(x+1)$

Step-by-step explanation:

we are given polynomial as

$p(x)=x^3+5x^2-x-5$

We can group first two terms and last two terms

$p(x)=(x^3+5x^2)-x-5$

We can factor out -1 from last two terms

$p(x)=(x^3+5x^2)-1* (x+5)$

We can see that x^2 is common in first two terms

so, we can factor out x^2 from first two terms

$p(x)=x^2(x+5)-1* (x+5)$

we can see x+5 is in both terms

so, we can factor out x+5

$p(x)=(x+5)(x^2-1)$

we can also factor it as

$p(x)=(x+5)(x-1)(x+1)$

Answer 2

Answer:

Answer:

P(x)=x^2(x+5)-(x+5)

P(x)=(x^2-1) (x+5)

P(x)=(x-1) (x+1) (x+5)

A. 269,60 -- 29.56; 28 hours
B. 9.50h 2 269,60; 29 hours
C. 269.60 + h 29.50; 31 hours
D. 269.60 2 9,50; 30 hours

Answers

Answer:I would believe it's the first choice. I'm not great with the inequalities though so it could be wrong. If you work 29 hours making $9.50, you make like $275 or something so it is greater than the $269.60 you need. :D
