x^2/x-4 - 7/x-4=0 *Please solve the rational expression. multipy both sides by (x-4) then you have x^2-7=0 x= +- sqrt 7
please help math
x/3-2/3=1/x *Solve the rational below. I really need help. multiply both sides by x. x^2/3 -2x/3 = 1 multiply both sides by 3 subtract three from each side x^2 -2x -3=0 (x-3)(x+1)=0 Then either of the factors can be zero, or x=3 or x=-1
Math 3 PLease Help
*Please solve the rational expression. x^2/x-4 - 7/x-4=0
Math 2 pLEASE HELP
y+2/y=1/y-5 *Please solve the rational equation. Done the same way as the previous post.
Math Help Please...
x/3-2/3=1/x *Solve the rational below. I really need help. Multiply through by 3x x^2 -2x = 3 And solve. I don't get it... can you explain it more.then I can help you Margie

Problem 3: 4x/(x+2) - 8/(x-1) What I did: Common denominator is: (x+2)(x-1) 4x(x-1)/(x+2)(x-1) - 8(x+2)/(x+2)(x-1) [4x(x-1) - 8(x+2)]/(x+2)(x-1) multiply the numerator out. 4x^2 -4x -8x-16 4x^2-12x-16 factor 4 out 4(x^2-3x-4) factor 4(x-4)(x+1) and that will reduce over the de...

Problem 2: (x+2)/(2x^2+5x+2) - (x-3)/(2x^2-5x-3) What I did: 2x^2+5x+2 factors are (2x+1)(x+2) 2x^2-5x-3 factors are (2x+1)(x-3) Then: (x+2)/(2x+1)(x+2) - (x-3)/(2x+1)x-3) So the common denominator is (2x+1)(x+2)(x-3) using that combine the fractions. I already knew the common...
BobPursley..here it is:
Problem 1: (x-2)/(3x+4) - 6x/(x+1) What I did: Common denominator is: (3x+4)(x+1) (x-2)(x+1)/(3x+4)(x+1) - 6x(3x+4)/(x+1)(3x+4) [(x-2)(x+1) - 6x(3x+4)] / (x+1)(3x+4) (x^2 - x - 2 - 18x^2 - 24x) / (x+1)(3x+4) x^2 - 18x^2 = -17x^2 -x - 24x = -25x (-17x^2 - 25x - 2) / (x+1)(3x+4)...
