It is 2a-b simplified
2b+b-4
You can not. That is already simplest form.
1/a = 1/b: cross multiplying gives a = b
A surd in the form a√b cannot, in general, be simplified.
b Γ b = bΒ²
4b
(a+b)2

It is 2a-b simplified
You cannot simplify them. If they are negative they have to stay negative.
7
You can't simplify that any more.
ab * -b = -ab^-2
b+c^2 There is no way to simplify that.
2b
2b+b-4
