I can't seem to get past this problem...

2x + 5

3x x-8

For the answer I keep getting something like: 17x-13

3x(x-8)

Thanks for your help!

Once you find the LCD, which you have done correctly, you have to multiply the numerator and denominator of each by the same factor:

2x (x-8) + 5 (3x)

3x (x-8) x-8 (3x)

2x^{2} - 16x + 8x = 2x^{2} -8x = (x)(2x -4) = 2x-4

(3x)(x-8) 3x^{2} - 24x (x)(3x-24) 3x-24

your answer = {2x(x-8) + 15x}/3x(x-8)

= (2x^{2}-16x+15x)/3x(x-8)

= (2x^{2}-x)/3x(x-8)

=x(2x-1)/3x(x-8)

=2x-1/(3(x-8))

The end answer is not right on this. Sorry multiplication error. Should be 2x-1/3x-24
