*(2x/(x^2-4)) + (5/2-x) - (1/2+x)\n*(2x/(x^2-4)) + (5/2-x)((2+x)/(2+x)) - (1/2+x)((2-x)/(2-x))\n*(2x/(x^2-4)) + (10+5x)/(4-x^2) - (2-x)/(4-x^2)\n*(2x/(x^2-4)) + (8+6x)/(4-x^2)\n\nyou should be able to get it from there

if 2x-1=T so x=(T+1)/2 \nf(T)=4((T+1/2)power to 2)-1 \nf(T)=4((T+1)power to 2)/4)-1\nf(T)=((T+1)power to 2 )-1\nf(T)= T power to 2+ 2T+1-1\nf(T)= T power to 2 + 2T\nwe can replace T with everything like x\n\nf(x)= x power to 2 + 2x

I hope you are trying to say x+2 = (2/3)(2x-1)..if it is correct then\n\n3(x+2) = 2(2x-1) --> 3x+6 = 4x - 2 --> 6+2 = 4x-3x --> 8 = x

= x / (x+6)(x+4)    +    2 / (x+4)\n\n = x + 2(x+6)  /  (x+6)(x+4)\n\n = 3x+12  /  (x+6)(x+4)\n\n = 3(x+4)  /  (x+6)(x+4)\n\n = 3  / (x+6)

=> 14x -8+5-9x=1-3x\n=> 14x-9x+3x=1+8-5\n=> 8x=4\n=> x=4/8=1/2=0.5\n\nCHEERS!

(8x^4 + x^2 + 9)/x^4\n= 8x^4/x^4 + x^2 / x^4 + 9/x^4\n= 8 + 1/x^2 + 9/x^4 \nor 8 + x^-2 + 9x^-4

2x - 2 = x^2 - 4x + 3\nSet one side equal to 0\n0 = x^2 - 6x + 5\nFactor\n0 = (x - 5)(x - 1)\nSet each factor equal to 0\n0 = x - 5              0 = x - 1\nSolve\n5 = x                  1 = x

OK,as the first one is already done,I am doing the rest for you\n4(2x-6)=x+2 =>8x-24=x+2  =>8x-x=2+24  =>7x=26  =>x=26/3=8 2/3  (3) 2(x+5)+1=3(x-1)+4   =>2x+10+1=3x-3+4 =>2x-3x=-3+4-10-1  => -x=-4  =>x=1  (5)x+6=4(4x-1)   =>x+6=16x-4  =>x-16x=-4-6  => -15x=-10  =>x=-10/-15=2/3 [after reducing]

x(x-3)/x(x+2) divided by (x-3)(x-2)/(x-2)(x+2)\nfrom first fraction curtail x \nfrom second fraction curtail (x-2) and we have\n(x-3)/(x+2) divided by (x-3)/(x+2), which is 1\nx^2 - 5x + 6 = (x-2)(x-3)\nx^2 - 4 = (x -2)(x+2)
