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 + )

Step-by-step explanation:

we are given polynomial as

We can group first two terms and last two terms

We can factor out -1 from last two terms

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

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

we can see x+5 is in both terms

so, we can factor out x+5

we can also factor it as

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

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

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

Step-by-step explanation:

where's the diagrams?

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
