PLEASE HELP ! Find the zeros of the given function.
photoshop1234 [79]

Answer:

-1, 4+i, 4-i

Step-by-step explanation:

x^4- 6x^3 + 2x^2 + 26x + 17

Using the rational root theorem

we see if 1, -1, -17 or 17 are roots

Check and see if 1 is a root

1^4- 6(1^3) + 2(1^2) + 26(1) + 17=0

1-6+2+26+17 does not equal 0  1 is not a root

-1

1^4- 6(-1^3) + 2(1^2) + 26(-1) + 17=0

1 +6 +2 -26+17 = 0

-1 is a root

Factor out (x+1)

(x+1) ( x^3-7x^2+9x+17)

Using the rational root theorem again on x^3-7x^2+9x+17

Checking -1

-1 -7 -9 +17=0

-1 is a root

(x+1) (x+1) (x^2-8x+17)

Using the quadratic on the last

8 ±sqrt(8^2 - 4(1)17)

--------------------------------

    2

gives imaginary roots

PLEASE HELP!!!!
alina1380 [7]

Answer:

B, D, E  

Step-by-step explanation:

-8x  -  6y = 10

  x + 7y =    9

You can multiply any of these equations by a constant without changing the solution.

B. 4x + 3y = -10 is equivalent to multiplying each side of the first equation by -½.

D. -16x - 12y = 20 is equivalent to multiplying each side of the first equation by 2.

E. 3x + 21y = 27 is equivalent to multiplying each side of the second equation by 3.

A. -2x + 7y = 9 is wrong. The signs don't match those of the second equation.

C. 24x + 18y = 10 is wrong. The signs don't match those of the first equation.

F. x - 14y = -18 is wrong. The coefficient of x should be -2.
