Question

Subtract Rational Function-
1/x-2 - 1/3x+4

My math is off, let me know my mistake please

1(3x+4)/(x-2)(3x+4) - 1(x-2)/(x-2)(3x+4)

3x+4-x-2/(x-2)(3x+4)

2x+2/(x-2)(3x+4) My Answer
2(x+3)/(x-2)(3x+4) Teachers Answer

Answer 1

(3x+4) - (x-2) / (3x+4)(x-2)

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


the numerator of -1(x-2)/(x-2)(3x+4)

should have been( -x+2) / (x-2)(3x+4)


Use paranthesis :)
