Did you mean?
2+ 4x / [(x+2)(x+3)] = 1/(x+2) + 3/(x+3)
If you did..

Multiply both sides by (x+2)(x+3)

2(x+2)(x+3) +4x = (x+3)+3(x+2)
2x^2+10x+12+4x = x+3+3x+6
2x^2+14x+12=4x+9
2x^2+10x+3 = 0
x = [-10 +/- sqrt(10^2-4*2*3)/4]
x = [-10 +/- sqrt(76)]/4
x = -5/2 +/- sqrt(19)/2
x ~ -.32 or x ~ -4.68

Here are the steps to get the answer.

(1) Rule out any impossible answers. In this case, you can rule out x = -2 and x = -3 as answers, because either would give you a zero denominator.

(2) Multiply both sides by the lowest-common denominator -- in this case, (x+2)(x+3). That gives you:

2(x+2)(x+3) + 4x = (x+3) + 3(x+2)

(3) Simplify each side, then collect all the terms on the left side, leaving you with zero on the right.

(4) If the resulting quadratic can be factored, factor it and use the Zero Product Law to determine your answers. If it can't be factored, however, then you can either complete the square or use the Quadratic Formula to get your result.

Good luck!

Mathmatical Proof that Barney is Satan
Given: Barney is a CUTE PURPLE DINOSAUR
Prove: Barney is Satanic

The Romans had no letter 'U' and used 'V' instead for printing, meaning the Roman representation for Barney would be:

CVTE PVRPLE DINOSAVR
Extracting the Roman numerals, we have:

C V V L D I V
Decimal Equivalents are:

100 5 5 50 500 1 5
Adding those numbers produces: 666

666 is the number of the beast.

Therefore, Barney is Satan.

x=y+2z assume then y=x-2z, then using the binomial theorem and applying the upper and lower limits to the equanomial coefficient of the upper and lower limits and using the corresponding variable to the binary value or hexa decimal value and then synthesising x we obtain y and z and thus the value of x is found again and compared with assumed x and then the upper and lower limits are solved and the answer is applied to the equation x-y-2z=0. and then the equation2+((4x)/(x+2)(x+3))=(1/x+2)+(3... is solved by suitable method of the users own method by the formula that if the solution set of the variable is proportional to the coeffiient of the variable then the coefficient of the variable is inversely proportional to the value of x and y and z where x and y and z are x and y and z respectively.
