T has points (2,1)(3,-2)(1,-1)

E1 has a scale factor of 3 and its Centre of Enlargement is (0,0). E2 has a scale factor of 0.5 and its centre of enlargement is (0,0).

I know how to do those, my question is how do you do E2E1 with a scale factor of 1.5 and centre of enlargement (0,0)?

or E1E2-scale factor of 1.5 and centre of enlargement (0,0)?
