Add: 3x+9/2x+6+8x+12/x^2+6x+9

Answer: X = sqrt[4]{/frac{36}{-34} }

Step-by-step explanation:

First

you are going to plus all the common denominators.

3x + 6x + 8x = 17x

6 + 9 = 15

Second

then we get the following equation

15 + 17x + 9/2x + 12/x^2

Thirst

then you pass the 17x to the other side with subtraction sign

-17x = 15 + 9/2x + 12/x^2

fourth

after that, the values which are dividing pass to the other side multiplying

-17x. 2x. x^2 = 15 + 9 + 12

fifth

If we resolve the equation in both sides we get the next values

-34x^4 = 36

sixth

then pass the - 34 to the other side dividing

x^4 = 36/-34

seventh

after that, pass the exponent of the (X) to the other side

X = sqrt[4]{/frac{36}{-34} }
