Step-by-step explanation:

5x + 2 + 3x = 8x + 2

3 + 17x + 8 = 17x + 11

19 + 6x + 2x = 8x + 19

14x + 7 + 4 = 14x + 11

9x - 3 - 7x + 4 = 2x + 1

12x + 3x - 6 - 7f = 15x - 7f - 6

14x + 7 - 3x = 11x + 7

13z + 6u + 8x + 19 - u = 13z + 5u + 8x + 19

3z + 6 + 4z + 9 + 8u = 7z + 8u + 15

2x + 8z + 13u + 6z + 4u = 2x + 14z + 17u

14y + 13x + 12y + 19x + 4 = 26y + 32x + 4

5x + 18 - 13y + 12x + 8y = 17x - 5y + 18

21v + 8 - 12v - 7 + 3t - t = 9v + 2t + 1

3t + v - t + 7v = 2t + 8v

-1 + 18x -3y + x + 9y = 19x + 6y - 1

4x + 5y + 5x + 10y = 9x + 15y

may someone help me ASAP? I am solving polynomial equations and I don't know how to do it, here is the equation... x^4+11x^2=3x^
koban [17]

<u>Answer:</u>

x=2\sqrt{2}, x=-2\sqrt{2}, x=4i, x=-4i

<u>Step-by-step explanation:</u>

x^4+11x^2=3x^2+128

First, we subtract 128 from both sides:

x^4+11x^2-128=3x^2

Then, we subtract 3x^2 from both sides:

x^4+8x^2-128=0

Rewrite the equation:

u^2+8u-128=0

Insert and solve:

u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i
