Quadratic Equations

If a = b (so I say)

And we multiply both sides by a

Then we’ll see that a

When with ab compared

Are the same. Remove b. OK?

Both sides we will factorize. See?

Now each side contains a – b.

We’ll divide through by (a

– b) and olT

a + b = b. Oh whoopee!

But since I said a = b

b + b = b you’ll agree?

So if b = 1

Then this sum I have done

Proves that 2 = 1. Q.E.D.

a = b

a = ab

a – b = ab – b

(a + b)(a – b) = b(a – b)

a + b = b

b + b = b
