How do we solve this one ? Solve for x :
$(a-b)x^2$- (a+b)x + 2b =0

Use the quadatic formula:

a = a - b, b = -(a + b), c = 2b.

Ohhhhh ....... that doesn't make sense does it? Why is that I wonder ......?

Let me start again:

Use the quadatic formula:

A = a - b, B = -(a + b), C = 2b.

Get it?

If $a \ne b$ use the quadratic formula, if $a=b\ne 0$, then the solution is $x=2b/(a+b)$.
