2-x+1/x-2-x-4/x+2 can be written as a single fraction in the form ax+b/x^2-4 where a and b are integers

work out the value of and and the value of b

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
