Question

28m^2=-8m

Answer 1

Note that 28m² = m(28m) = -8m

Now cancel m out.

28m = -8

Divide both sides by 28.

m = -8/28 = -2/7

Answer 2

Is this clear?

Answer 3

So... the answer would be (0, -2/7)?

Answer 4

0 and -2/7, yes.

Answer 5

So why are only 2 of the m's cancelled out? Why not the one next to 28?

Answer 6

m² = m·m

So if you divide both sides by m, you will get 28m = -8

Answer 7

OH! Right. Sorry, I was thinking straight. Thanks!!
