Answer 2

Question number 1:

The answer is A.

A.) 

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

=(3X-1)(X-4)-(X+1)(X+2)/(X+2)(X-4)

=EXPAND (3X-1)(X-4)-(X+1)(X+2)

3X^2 - 12X -1X+4=3X^2 - 13X + 4

-X^2-2X-1X-2=-X^2-3X-2

3x^2-x^2=2x^2

-13x-3x= -16x

4-2=2

The denominator numbers stay the same

To find the value of x you can put the equation in the graphic calculator.

Final answer=2X^2-16X+2/(X+2)(X-4)
