Factor the polynomial function over the complex numbers. f(x)=x^4-x^3-2x−4 Enter your answer in the box. f(x) = The answer is: (

Vladimir79 [104]

Answer:

Factors: $(x+i\sqrt2)(x-i\sqrt2)(x+1)(x-2)=0$

Step-by-step explanation:

We are given a polynomial:

$f(x)=x^4-x^3-2x-4$

We have to factor the given polynomial into its complex factors.

The factorization can be done as follows:

$f(x)=x^4-x^3-2x-4 = 0\\x^4-x^3-2x-4 = 0\\x^4-4-x^3-2x=0\\\text{Identity: }a^2-b^2 = (a+b)(a-b)\\(x^4-4)-(x^3+2x) = 0\\(x^2+2)(x^2-2)-x(x^2+2) = 0\\(x^2+2)(x^2-2-x) = 0\\(x^2+2)(x^2-x-2) = 0\\(x^2+2)(x^2-2x-+x-2) = 0\\(x^2+2)((x(x-2)+1(x-2))=0\\(x^2+2)(x+1)(x-2)=0\\\text{Identity: }a^2-b^2 = (a+b)(a-b)\\(x^2-(\sqrt{-2})^2)(x+1)(x-2)=0\\(x+i\sqrt2)(x-i\sqrt2)(x+1)(x-2)=0$

Look at the equation 4x - 8.4 = 2x + 5. The terms 4x and 2x are like terms

xz_007 [3.2K]

In form ax + b = c: 2x - 8.4 = 5

Solution to equation: x = 6.7

Step-by-step explanation:

4x - 8.4 = 2x + 5

2x - 8.4 = 5

2x = 13.4

x = 6.7

On a number line, suppose point E has a coordinate of 4, and EG = 11. What are the possible coordinates of point G?

navik [9.2K]

Answer:

-7, 15

Step-by-step explanation:

The positive difference between E and G is 11.

<h3>Solution</h3>

G - E = 11

G = 11 + E = 11 + 4

G = 15 . . . . . . . . . . . . . when G is right of E

E - G = 11

E - 11 = G = 4 - 11

G = -7 . . . . . . . . . . . . when G is left of E

Possible coordinates for G are -7 and 15.

you walk into a room.on the bed,there 2 dogs, 4 cat, a girrafe, 5 cows and a duck.there are also three chickens flying above the

Tems11 [23]

Answer:

50 legs

Step-by-step explanation:

We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate $2(4)+4(4)+1(4)+5(4)+1(2)+3(2)$ , right?

Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want $2(4)+4(4)+1(4)+5(4)+1(2)$ .

We multiply it out to get $8+16+4+20+2$ .

We add these up to get $50$ .

So, our answer is $\boxed{50}$ legs.
