Please help me solve this using long division. (r4 - r2 + 4) ÷ (r2 - r + 2)
I got the first digits r^2 + r, and then I got stuck

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.
